Takashi Iwai 0599313e26 ALSA: usb-audio: Make sure to stop endpoints before closing EPs
At the PCM hw params, we may re-configure the endpoints and it's done
by a temporary EP close followed by re-open.  A potential problem
there is that the EP might be already running internally at the PCM
prepare stage; it's seen typically in the playback stream with the
implicit feedback sync.  As this stream start isn't tracked by the
core PCM layer, we'd need to stop it explicitly, and that's the
missing piece.

This patch adds the stop_endpoints() call at snd_usb_hw_params() to
assure the stream stop before closing the EPs.
