As part of formating the mass storage device, Host sends the INQUIRY
scsi command. As per the standard, the command length for this
command should be 6 bytes, whereas the Vista host sends 12 bytes.
When the command length of the command is not equal to the standard
length, the device sends a phase error as part of the status phase.
When the host receives a phase error, it re-enumerates, hence the
error.
If the command is INQUIRY, and the command length is 12 bytes,
treating this as a good command and not sending the phase error
to the host fixes this issue.

Pulling in some code from file_storage.c, we now handle interface changes
in do_set_config(), which is now not called until any pending requests have
been successfully completed or cancelled.
This fixes a race condition that resulted in usb_ep_free_request() being called
while the request is still busy.

The old code did not allways disable interrupts when called from thread
context, but tried to lock the same spinlock from interrupt context.
This was merged from a change to drivers/usb/function/mass_storage.c
in the android-msm-2.6.29 branch.
