realtek: rtl93xx: Send per port packets on physical port

If link aggregation with LACP is activated, we must send out the LACP
packets on the physical port and not on a logic port. Otherwise, the per
port packets might be (rebalanced) between the different ports in a link
aggregation group.

Such rebalancing breaks 802.3ad and will leave ports in a churned state.
