blkcg: make blkcg_activate_policy() allow NULL ->pd_init_fn blkg_create() allows NULL ->pd_init_fn() but blkcg_activate_policy() doesn't. As both in-kernel policies implement ->pd_init_fn, it currently doesn't break anything. Update blkcg_activate_policy() so that its behavior is consistent with blkg_create().
