fsnotify: fsnotify_obtain_group should be fsnotify_alloc_group
fsnotify_obtain_group was intended to be able to find an already existing group. Nothing uses that functionality. This just renames it to fsnotify_alloc_group so it is clear what it is doing. Signed-off-by: Eric Paris <eparis@redhat.com>
