Tejun Heo 159749937a blkcg: make root blkcg allocation use %GFP_KERNEL ...

Currently, blkcg_activate_policy() depends on %GFP_ATOMIC allocation
from __blkg_lookup_create() for root blkcg creation.  This could make
policy fail unnecessarily.

Make blkg_alloc() take @gfp_mask, __blkg_lookup_create() take an
optional @new_blkg for preallocated blkg, and blkcg_activate_policy()
preload radix tree and preallocate blkg with %GFP_KERNEL before trying
to create the root blkg.

v2: __blkg_lookup_create() was returning %NULL on blkg alloc failure
   instead of ERR_PTR() value.  Fixed.
