net/mlx5e: Clear mirred devices array if the rule is split
In the cited commit, the mirred devices are recorded and checked while parsing the actions. In order to avoid system crash, the duplicate action in a single rule is not allowed. But the rule is actually break down into several FTEs in different tables, for either mirroring, or the specified types of actions which use post action infrastructure. It will reject certain action list by mistake, for example: actions:enp8s0f0_1,set(ipv4(ttl=63)),enp8s0f0_0,enp8s0f0_1. Here the rule is split to two FTEs because of pedit action. To fix this issue, when parsing the rule actions, reset if_count to clear the mirred devices array if the rule is split to multiple FTEs, and then the duplicate checking is restarted.
