tinyalsa: fix double free crash in pcm_close
Pcm data and snd_node will be released if pcm_open() encounters error
condition after plugin open, but valid pcm pointer is still returned.
If client invokes pcm_close() later, pcm data and snd_node will be freed
again which results into crash. Add NULL pointer check to avoid same
resource being freed twice.
