Alexey Khoroshilov e6028db014 mei: fix mismatch in mutex unlock-lock in mei_amthif_read()
Users of mei_amthif_read() expect it leaves dev->device_lock held,
while there is a path where mei_amthif_read() unlocks device_lock
and returns -ERESTARTSYS.

The patch move code locking device_lock back before the return.
