Jianbo Liu 88895d4247 net/sched: flower: Add lock protection when remove filter handle 
[ Upstream commit 1fde0ca3a0de7e9f917668941156959dd5e9108b ]

As IDR can't protect itself from the concurrent modification, place
idr_remove() under the protection of tp->lock.

Fixes: 08a0063df3ae ("net/sched: flower: Move filter handle initialization earlier")
