inotify: do not recurse in handle_timeout(): call it explicitely, not in scan()
When in handle_timeout, scan() is called when a repertory is created/modified.
But the first line of scan calls handle_timeout.
This had the consequence of calling recursively handle_timeout:
* several calls to read_events (but only the first one retrieves events)
* every time that an event is queued for a deferred action, the next time that
scan() is called, handle_timeout is called, the event queue is treated,
even if all the events haven't been read/queued yet. This could lead to
inconsistencies
