ether82557: don't turn off promisc mode when mcast table is not empty

Browse source 
the driver doesnt implement multicast filter, but just turns
on promiscuous mode when a multicast address is added. but this
breaks when one actually enables and then disables promiscuous
mode with say, running snoopy.

we have to keep promisc mode active as long as multicast table
is not empty.
