ALSA: usb-audio: Clean up endpoint setups at PCM prepare
This patch cleans up the superfluous checks and calls for setting up
the endpoints at PCM prepare callback:
- Drop stop_endpoints() and sync_pending_stops() calls; the stream is
guaranteed to have been already stopped and synced at each PCM
prepare call by ALSA PCM core
- Call snd_usb_endpoint_prepare() unconditionally;
the check for endpoint->need_setup is done in
snd_pcm_hw_endpoint_prepare() itself
- Apply snd_usb_set_format_quirk() only when the endpoint is actually
set up (i.e. the return code from snd_usb_endpoint_prepare() > 0)
- Move a few lines back into snd_usb_pcm_prepare();
it's even easier to follow than a small useless function
