[riot-notifications] [RIOT] net/ng_netdev_eth: added missing NULL ptr check (#3238)

When calling `_addr_set_multicast`, payload may be NULL. But `_addr_set_multicast` dereferences `payload` in its first line of implementation. So making sure here, that we only call it, if `payload` is not NULL. 

Maybe it might make sense to move the NULL pointer check into `_addr_set_multicast`? I dont have an opinion here...
