[PATCH net-next v4 10/15] net: dsa: tag_sja1105: prefer precise source port info on SJA1110 too

From: Vladimir Oltean <vladimir.oltean@nxp.com>

Now that dsa_8021q_rcv() handles better the case where we don't
overwrite the precise source information if it comes from an external
(non-tag_8021q) source, we can now unify the call sequence between
sja1105_rcv() and sja1110_rcv().

This is a preparatory change for creating a higher-level wrapper for the
entire sequence which will live in tag_8021q.
