gestures: don't send swipe gestures when gestures are disabled

Introduced in 6ad303b as part of an code flow optimization, causing any 3+
finger gesture to be posted as swipe gesture, even when gestures are disabled.
However, the event is filtered in the higher levels with a bug message printed
to the log.

Don't post swipe gestures for devices where gestures are disabled.
