Since the slave unicast address is synced to hardware and to the DSA
master during dsa_slave_open(), this means that a call to
dsa_slave_set_mac_address() while the slave interface is down will
result to a call to dsa_port_standalone_host_fdb_del() and to
dev_uc_del() for the MAC address while there was no previous
dsa_port_standalone_host_fdb_add() or dev_uc_add().
This is a partial revert of the blamed commit below, which was too
aggressive.
