pcm: rate - rewrite the may_wait_for_avail_min callback for the rate plugin

Browse source 
Shuffle the code to avoid special conditions using the plugin type
in the generic plugin code. The rate plugin has the own
may_wait_for_avail_min callback implementation now.

Fixes: d21e0e01 ("pcm: plugin - fix avail_min calculation on rate plugin")
