inotify: handle_event: do not use event and fd parameters.
event is particularly confusing given the context (is it an inotify event?
a polling event?) and is never used. Remove it.
fd has very little use, and it gives the false impression that event handling
depends on fd. It's wrong: the same behavior is triggered, for all events.
