Two fixes that are result of the recent discussions [1][2].

First adds missing locking around snd_pcm_stop() while the second fix
sets substream state to DISCONNECTED if any suspend/resume related
operation fails so that userspace has means to be aware that something
went wrong during said operation.

Changes in v3:
- added a comment why non-_irq() locking is used around snd_pcm_stop()

Changes in v2:
- __snd_pcm_set_state() replaced direct assignments of PCM state
