Issue:
When scene mode is Landscape/Sunset, Backend AF mode is
set to Infinity and AF state is INACTIVE and then when
APP calls do AF, focus state is still Inactive and since
there is no change in AF state, HAL not sending the state
to frameworks and APP got stuck.
Fix:
Check backend AF mode is INFINITY and if its Active AF call
then send the corresponding AF INACTIVE state to frameworks.
