Subject: net/mlx5: E-switch, Fix missing set of split_count when forward to
 ovs internal port
Patch-mainline: v6.3-rc3
Git-commit: 28d3815a629cbdee660dd1c9de28d77cb3d77917
References: jsc#PED-1549

Rules with mirror actions are split to two FTEs when the actions after the mirror
action contains pedit, vlan push/pop or ct. Forward to ovs internal port adds
implicit header rewrite (pedit) but missing trigger to do split.

Fix by setting split_count when forwarding to ovs internal port which
will trigger split in mirror rules.

Fixes: 27484f7170ed ("net/mlx5e: Offload tc rules that redirect to ovs internal port")
