This patch adds the AirVasT USB wireless devices 124a:4026
to the list of supported devices. It's using the ISL3886
usb firmware. Without this modification, the wiki adapter
is not recognized.

First set of patches for 5.3, but not that many patches this time.
This pull request fails to compile with the tip tree due to
ktime_get_boot_ns() API changes there. It should be easy for Linus to
fix it in p54 driver once he pulls this, an example resolution here:
https://lkml.kernel.org/r/20190625160432.533aa140@canb.auug.org.au
Major changes:
airo
* switch to use skcipher interface
p54
* support boottime in scan results
rtw88
* add fast xmit support
* add random mac address on scan support
rt2x00
* add software watchdog to detect hangs, it's disabled by default

The syzbot fuzzer found a bug in the p54 USB wireless driver. The
issue involves a race between disconnect and the firmware-loader
callback routine, and it has several aspects.
One big problem is that when the firmware can't be loaded, the
callback routine tries to unbind the driver from the USB _device_ (by
calling device_release_driver) instead of from the USB _interface_ to
which it is actually bound (by calling usb_driver_release_interface).
The race involves access to the private data structure. The driver's
disconnect handler waits for a completion that is signalled by the
firmware-loader callback routine. As soon as the completion is
signalled, you have to assume that the private data structure may have
been deallocated by the disconnect handler -- even if the firmware was
loaded without errors. However, the callback routine does access the
private data several times after that point.
Another problem is that, in order to ensure that the USB device
structure hasn't been freed when the callback routine runs, the driver
takes a reference to it. This isn't good enough any more, because now
that the callback routine calls usb_driver_release_interface, it has
to ensure that the interface structure hasn't been freed.
Finally, the driver takes an unnecessary reference to the USB device
structure in the probe function and drops the reference in the
disconnect handler. This extra reference doesn't accomplish anything,
because the USB core already guarantees that a device structure won't
be deallocated while a driver is still bound to any of its interfaces.
To fix these problems, this patch makes the following changes:
Call usb_driver_release_interface() rather than
device_release_driver().
Don't signal the completion until after the important
information has been copied out of the private data structure,
and don't refer to the private data at all thereafter.
Lock udev (the interface's parent) before unbinding the driver
instead of locking udev->parent.
During the firmware loading process, take a reference to the
USB interface instead of the USB device.
Don't take an unnecessary reference to the device during probe
(and then don't drop it during disconnect).

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.
