[PATCH 01/12] blkcg: fix minor bug in blkg_alloc()

[Tejun Heo]

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.
