net/qede: fix multicast drop in promiscuous mode

After enabling promiscuous mode all packets whose destination MAC
address is a multicast address were being dropped. This fix configures
H/W to receive all traffic in promiscuous mode. Promiscuous mode also
overrides allmulticast mode on/off status.
