Series pcm: Fix missing appl_ptr and hw_ptr updates in snd_pcm_status() | expand

Commit Message

Takashi Iwai Jan. 22, 2021, 2:48 p.m. UTC 
The snd_pcm_status() of the ioplug doesn't return the current
positions of hw_ptr and appl_ptr as advertised.  Fix it by copying the
current values stored in the plugin data.
