net/mlx5: E-switch, Fix missing set of split_count when forward to ovs internal port

BugLink: https://bugs.launchpad.net/bugs/2016876
[ Upstream commit 28d3815a629cbdee660dd1c9de28d77cb3d77917 ]

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.
