hal: retry failed MBDRC cal level
- in the start of the playback since usecase list is empty
or not populated with the current usecase (which will be added
on the first write) unless volume is changed when playing music
correct gain level is not selected
- cache gain level on failure and trigger set gain level when a
new usecase is added
