Takashi Iwai c318c81453 Revert "ALSA: usb-audio: Fix race at stopping the stream" 
[ Upstream commit f8114f8583 ]

This reverts commit 16200948d8.

The commit was intended to cover the race condition, but it introduced
yet another regression for devices with the implicit feedback, leading
to a kernel panic due to NULL-dereference in an irq context.

As the race condition that was addressed by the commit is very rare
and the regression is much worse, let's revert the commit for rc1, and
fix the issue properly in a later patch.
