Clemens Ladisch aee7040018 ALSA: isight: fix hang when unplugging a running device
When aborting a PCM stream, the xrun is signaled only if the stream is
running.  When disconnecting a PCM stream, calling snd_card_disconnect()
too early would change the stream into a non-running state and thus
prevent the xrun from being noticed by user space.

To prevent this, move the snd_card_disconnect() call after the xrun.

After handling a received packet, we want to resubmit the same packet,
so do not increase the packet index too early.

Clemens Ladisch 03c29680d4 ALSA: isight: fix isight_pcm_abort() crashes
Fix crashes in isight_pcm_abort() that happen when the driver tries to
access isight->pcm->runtime which does not exist when the device is not
open.  Introduce a new field pcm_active to track this state.
