blkcg: fix minor bug in blkg_alloc()
blkg_alloc() was mistakenly checking blkcg_policy_enabled() twice. The latter test should have been on whether pol->pd_init_fn() exists. This doesn't cause actual problems because both blkcg policies implement pol->pd_init_fn(). Fix it. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Vivek Goyal <vgoyal@redhat.com>
