net_sched: fix a missing idr_remove() in u32_delete_key()
When we delete a u32 key via u32_delete_key(), we forget to call idr_remove() to remove its handle from IDR. Fixes: e7614370d6f0 ("net_sched: use idr to allocate u32 filter handles") Reported-by: Marcin Kabiesz <admin@hostcenter.eu> Tested-by: Marcin Kabiesz <admin@hostcenter.eu> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
