Paul Blakey 8258d2da9f cls_flower: Fix incorrect idr release when failing to modify rule 
When we fail to modify a rule, we incorrectly release the idr handle
of the unmodified old rule.

Fix that by checking if we need to release it.

Fixes: fe2502e49b ("net_sched: remove cls_flower idr on failure")
