pcm: plugin status - fix the return value (regression)

Browse source 
The snd_pcm_plugin_avail_update() error code in snd_pcm_plugin_status()
should not be reported to the caller. The state errors can be determined
using the state member in the status structure.

Fixes: 4f90392f07 ("pcm: fix the snd_pcm_plugin_status() avail and delay fields")
