ext4: make mb_optimize_scan option work with set/unset mount cmd
After moving to the new mount API, mb_optimize_scan mount option
handling was not working as expected due to the parsed value always
being overwritten by default. Refactor and fix this to the expected
behavior described below:
* mb_optimize_scan=1 - On
* mb_optimize_scan=0 - Off
* mb_optimize_scan not passed - On if no. of BGs > threshold else off
* Remounts retain previous value unless we explicitly pass the option
with a new value
Fixes: cebe85d570cf ("ext4: switch to the new mount api")
