bonding: do not allow rlb updates to invalid mac

[ Upstream commit 4fa8667ca3989ce14cf66301fa251544fbddbdd0 ]

Make sure multicast, broadcast, and zero mac's cannot be the output of rlb
updates, which should all be directed arps. Receive load balancing will be
collapsed if any of these happen, as the switch will broadcast.
