inotify: fix coalesce duplicate events into a single event in special case
If we do rename a dir entry, like this: rename("/tmp/ino7UrgoJ.rename1", "/tmp/ino7UrgoJ.rename2") rename("/tmp/ino7UrgoJ.rename2", "/tmp/ino7UrgoJ") The duplicate events should be coalesced into a single event. But those two events do not be coalesced into a single event, due to some bad check in event_compare(). It can not match the two NULL inodes as the same event.
