Syzbot reported an slab-out-of-bounds Read in thrustmaster_probe() bug.
The root case is in missing validation check of actual number of endpoints.
Code should not blindly access usb_host_interface::endpoint array, since
it may contain less endpoints than code expects.
Fix it by adding missing validaion check and print an error if
number of endpoints do not match expected number

Many HID drivers assume that the HID device assigned to them is a USB
device as that was the only way HID devices used to be able to be
created in Linux. However, with the additional ways that HID devices
can be created for many different bus types, that is no longer true, so
properly check that we have a USB device associated with the HID device
before allowing a driver that makes this assumption to claim it.

Add support for proper initialization of some Thrustmaster wheels that
appear like a "Thrustmaster FFB Wheel" (044f:b65d) to the host. When the
device is connected a special usb request is sent, this request makes the
wheel disconnect and reappear to the host as the "real wheel".
For example: a T150 will re-appear as 044f:b677 and a T300 as 044f:b66e
