Set types bitmap:ipmac and hash:ipmac check that MAC addresses
are not all zeroes.
Introduce one missing check, and make the remaining ones
consistent, using is_zero_ether_addr() instead of comparing
against an array containing zeroes.
This was already done for hash:mac sets in commit 26c97c5d8dac
("netfilter: ipset: Use is_zero_ether_addr instead of static and
memcmp").

ipmac sets
There doesn't seem to be any reason to restrict MAC address
matching to source MAC addresses in set types bitmap:ipmac,
hash:ipmac and hash:mac. With this patch, and this setup:
ip netns add A
ip link add veth1 type veth peer name veth2 netns A
ip addr add 192.0.2.1/24 dev veth1
ip -net A addr add 192.0.2.2/24 dev veth2
ip link set veth1 up
ip -net A link set veth2 up
ip netns exec A ipset create test hash:mac
dst=$(ip netns exec A cat /sys/class/net/veth2/address)
ip netns exec A ipset add test ${dst}
ip netns exec A iptables -P INPUT DROP
ip netns exec A iptables -I INPUT -m set --match-set test dst -j ACCEPT
ipset will match packets based on destination MAC address:
# ping -c1 192.0.2.2 >/dev/null
# echo $?
0
