spa: param: infer raw audio channels from position if unset

Browse source 
The behavior before b8eeb2db45 was that spa_audio_info_raw_update()
always sets audio.channels when audio.position is updated.  The new
behavior does not set audio.channels when parsing audio.position.

This breaks things e.g. when combine-sink and loopback nodes are created
with only audio.position specified.

Restore the previous behavior.
