Don't start fingerprint for FOD devices early

commit 5cece533 causes fingerprint to start early
while going to sleep and this is not the expected behaviour for devices
with FOD since we have to apply DIM and HBM simultaneously which causes
device to give flicker effect while putting phone to sleep.
