Takashi Iwai d3a9803bc7 ALSA: usb-audio: Fix racy list management in output queue 
[ Upstream commit 5b6cc38f3f3f37109ce72b60bda215a5f6892c0b ]

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: 8fdff6a319 ("ALSA: snd-usb: implement new endpoint streaming model")
