fsnotify: use kmem_cache_zalloc to simplify event initialization
fsnotify event initialization is done entry by entry with almost everything set to either 0 or NULL. Use kmem_cache_zalloc and only initialize things that need non-zero initialization. Also means we don't have to change initialization entries based on the config options. Signed-off-by: Eric Paris <eparis@redhat.com>
