ALSA: usb-audio: Fix racy list management in output queue
The linked list entry from FIFO is peeked at
queue_pending_output_urbs() but the actual element pop-out is
performed outside the spinlock, and it's potentially racy.
Do delete the link at the right place inside the spinlock.
Fixes: 8fdff6a319e7 ("ALSA: snd-usb: implement new endpoint streaming model")
