Allow udfps when strong auth is required

Browse Source 
Only disallow UDFPS usage if the device is
in lockdown or reboot. Otherwise, (for reasons like TIMEOUT
or SOME_AUTH_REQUIRED_AFTER_USER_REQUEST), we
allow the user to use fingerprint to authenticate; however,
the we will immediately bring up the bouncer instead of entering the
device.
