net: dsa: fix oops while probing Marvell DSA switches
Fix an oops in dsa_port_phylink_mac_change() caused by a combination
of a20f997010c4 ("net: dsa: Don't instantiate phylink for CPU/DSA
ports unless needed") and the net-dsa-improve-serdes-integration
series of patches 65b7a2c8e369 ("Merge branch
'net-dsa-improve-serdes-integration'").
