stmmac: fix changing mac address
Without the IFF_LIVE_ADDR_CHANGE flag being set, the network code
disallows changing the mac address while the interface is UP.
Consequences are, for instance, that the interface can't be used
in a failover bond.
Add the missing flag to net_device priv_flags.
Tested on Intel Elkhart Lake with default settings, as well as with
failover and alb mode bonds.
