fsnotify: Fix detection whether overflow event is queued
fsnotify: Fix detection whether overflow event is queued

Currently we didn't initialize event's list head when we removed it from
the event list. Thus a detection whether overflow event is already
queued wasn't working. Fix it by always initializing the list head when
deleting event from a list.
