net: stmmac: move stmmac_check_ether_addr() to driver probe
stmmac_check_ether_addr() checks the MAC address and assigns one in driver open(). In many cases when we create slave netdevice, the dev addr is inherited from master but the master dev addr maybe NULL at that time, so move this call to driver probe so that address is always valid.
