When EVDEV_SUPPORT was introduced, the USB transfers may be running after the main FIFO is closed. In connection to this a race may appear which can lead to use-after-free scenarios. Fix this for all FIFO consumers by initializing and resetting the FIFO queues under the lock used by the client. Then the client driver will see an empty queue in all cases a race may appear.
