net: stmmac: xgmac: fix missing IFF_MULTICAST checki in dwxgmac2_set_filter
Without checking for IFF_MULTICAST flag, it is wrong to assume multicast
filtering is always enabled. By checking against IFF_MULTICAST, now
the driver behaves correctly when the multicast support is toggled by below
command:-
ip link set <devname> multicast off|on
