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. Signed-off-by: Jan Kara <jack@suse.cz>
