[netdrvr] b44: handle excessive multicast groups
If there are more than B44_MCAST_TABLE_SIZE groups in the dev->mc_list,
it will only listen to the first B44_MCAST_TABLE_SIZE that it sees.
This change makes the driver go into RXCONFIG_ALLMULTI mode if there
are more than B44_MCAST_TABLE_SIZE groups being subscribed to, similar
to other network drivers.
