Peter Hutterer e961c1ff5c debounce: handle a timeout in MAYBE_SPURIOUS state ...

Sequences to trigger:
- spurious debouncing is enabled
- release a button in IS_DOWN state -> RELEASE_DELAYED
- short timeout triggers RELEASE_WAITING

If a button press now comes before the long timeout expires, we transition to
MAYBE_SPURIOUS where the long timeout may expire. In that case we should
transition to pressed state again.
