When new firmware gets flashed, its status is unreliable, "not
committed". In order to become "committed" (verified), a firmware must
be committed. If a firmware is not committed, then the next boot
reverts back to the previous firmware.
When a new firmware gets flashed, its status is marked as, "first_boot".
That is an unreliable (uncommitted) firmware. A user may choose
to revert back to the previous committed firmware on the subsequent
boots. Clicking on the "commit" button calls "mg_ota_commit()" function
which commits the firmware.
