RotationLock: Use controller to determine next state

mState.value seems to reset when rotating the screen.
This results in a glitching rotation lock tile,
which has to be tapped a second time for it to lock
the rotation again.

Set the value based on the current rotation lock state
to keep it in sync with the current setting and the UI
state.
