net: dsa: tag_xrs700x: use the dsa_xmit_port_mask() helper 

The "xrs700x" is the original DSA tagging protocol with HSR TX
replication support, we now essentially move that logic to the
dsa_xmit_port_mask() helper. The end result is something akin to
hellcreek_xmit() (but reminds me I should also take care of
skb_checksum_help() for tail taggers in the core).

The implementation differences to dsa_xmit_port_mask() are immaterial.
