blkcg: kill unused field nr_undestroyed_grps
'nr_undestroyed_grps' in struct throtl_data was used to count the number of throtl_grp related with throtl_data, but now throtl_grp is tracked by blkcg_gq, so it is useless anymore. Signed-off-by: Hou Tao <houtao1@huawei.com> Signed-off-by: Jens Axboe <axboe@fb.com>
