blk-cgroup: delay blk-cgroup initialization until add_disk
There is no need to initialize the cgroup code before the disk is marked
live. Moving the cgroup initialization earlier will help to have a
fully initialized struct device in the gendisk for the cgroup code to
use in the future. Similarly tear the cgroup information down in
del_gendisk to be symmetric and because none of the cgroup tracking is
needed once non-passthrough I/O stops.
