blkcg: kill blkio_list and replace blkio_list_lock with a mutex
With blkio_policy[], blkio_list is redundant and hinders with per-queue policy activation. Remove it. Also, replace blkio_list_lock with a mutex blkcg_pol_mutex and let it protect the whole [un]registration. This is to prepare for per-queue policy activation and doesn't cause any functional difference.
