af_packet: Teach to listen for multiple unicast addresses.
The the PACKET_ADD_MEMBERSHIP and the PACKET_DROP_MEMBERSHIP setsockopt
calls for af_packet already has all of the infrastructure needed to subscribe
to multiple mac addresses. All that is missing is a flag to say that
the address we want to listen on is a unicast address.
So introduce PACKET_MR_UNICAST and wire it up to dev_unicast_add and
dev_unicast_delete.
Additionally I noticed that errors from dev_mc_add were not propagated
from packet_dev_mc so fix that.
