[PATCH] change inotifyfs magic as the same magic is used for futexfs

[Andrey Mirkin <amirkin@sw.ru>]

From: Andrey Mirkin <major@openvz.org>

Right now futexfs and inotifyfs have one magic 0xBAD1DEA, that looks a little 
bit confusing.
Use 0xBAD1DEA as magic for futexfs and 0x2BAD1DEA as magic for inotifyfs.
