[PATCH net-next] net: dsa: sja1105: fix error return code in sja1105_cls_flower_add()

['w00385741]

From: Wei Yongjun <weiyongj...@huawei.com>

The return value 'rc' maybe overwrite to 0 in the flow_action_for_each
loop, the error code from the offload not support error handling will
not set. This commit fix it to return -EOPNOTSUPP.

Fixes: 6a56e19902af ("flow_offload: reject configuration of packet-per-second 
policing in offload drivers")
