inotify: drop user watch count when a watch is removed

Browse Source 
The inotify rewrite forgot to drop the inotify watch use cound when a watch
was removed.  This means that a single inotify fd can only ever register a
maximum of /proc/sys/fs/max_user_watches even if some of those had been
freed.
