Unlock overlay buffers before going to suspend

Browse Source 
In video playback through overlay, it is observed that, during
suspend/resume, genlock TIMEOUT errors are seen at the component
level.

drawLayerUsingOverlay() function locks buffers, but doesn't unlock
them, before going to suspend, making the genlock_lock_buffer calls
from video component to fail.

Unlock any overlay buffers before going to suspend.
