The main bug was that 'blk_cleanup_queue()' was called while the block
device could still be in use, for example, because the card was removed
while files were still open.
In addition, to be sure that 'mmc_request()' will get called for all new
requests (so it can error them out), the queue is emptied during cleanup.
This is done after the worker thread is stopped to avoid racing with it.
Finally, it is not a device error for this to be happening, so quiet the
(sometimes very many) error messages.

When a card is removed before mmc_blk_probe() has called add_disk(), then
the minor field is uninitialized and has value 0. This caused
mmc_blk_put() to always release devidx 0 even if 0 was still in use. Then
the next mmc_blk_probe() used the first free idx of 0, which oopses in
sysfs, since it is used by another card.

Bail out if we don't find an enclosing IOC. Previously, if we didn't
find one, we tried to set things up using garbage for the SBA/IOC register
address, which causes a crash.
This crash only happens if firmware supplies a defective ACPI namespace, so
it doesn't fix any problems in the field.

Commit 15b8dd53f5 changed the string in info->hardware_id from a static
array to a pointer and added a length field. But instead of changing
"sizeof(array)" to "length", we changed it to "sizeof(length)" (== 4),
which corrupts the string we're trying to null-terminate.
We no longer even need to null-terminate the string, but we *do* need to
check whether we found a HID. If there's no HID, we used to have an empty
array, but now we have a null pointer.
The combination of these defects causes this oops:
Unable to handle kernel NULL pointer dereference (address 0000000000000003)

so for some errors.
