net/sched: avoid double free on matchall reoffload 

Avoid freeing cls_mall.rule twice when failing to setup flow_action
offload used in the hardware intermediate representation. This is
achieved by returning 0 when the setup fails but the skip software
flag has not been set.

Fixes: f00cbf1968 ("net/sched: use the hardware intermediate representation for matchall")
