ALSA: pcm: Call sync_stop at disconnection
The PCM core should perform the sync for the pending stop operations
at disconnection. Otherwise it may lead to unexpected access.
Currently the old user of sync_stop, USB-audio driver, has its own
sync, so this isn't needed, but it's better to guarantee the sync in
the PCM core level.
This patch adds the missing sync_stop call at PCM disconnection
callback. It also assures the IRQ sync if it's specified in the
card. snd_pcm_sync_stop() is slightly modified to be called also for
any PCM substream object now.
Fixes: 1e850beea278 ("ALSA: pcm: Add the support for sync-stop operation")
