Minor Input:inhibitInput followup to #9065 (#9139)

* GestureDetector: Downgrade probeClockSource log messages to debug

We're seeing a bit more of 'em between autostandby and inhibitInput now,
and the whole thing was implemented long enough ago that it's no longer
critical to see this in random non-debug logs ;).

* Input: Reset gesture state in inhibitInput

Should prevent bogus gestures when re-enabling the handlers if we were
called in the middle of gesture detection.
