fsnotify: initialize mask in fsnotify_perm
akpm got a warning the fsnotify_mask could be used uninitialized in fsnotify_perm(). It's not actually possible but his compiler complained about it. This patch just initializes it to 0 to shut up the compiler. Reported-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Eric Paris <eparis@redhat.com>
