Fix Missing finger up event on UDFPS when the FPS triggered in AoD

When the device is woken up from AOD mode by a long press to
wake up gesture on the fingerprint sensor, FPS HAL set a flag.

This flag allows the kernel driver to track the finger's status and
notify the fingerprint driver when the finger is lifted from sensor.

HAL clear this flag each time the system registers the wake-up gesture.
Previous ag/28551525 change broke the behavor, and where the expected
immediatelyReRegister was always "false"
