netfilter: ipset: Actually allow destination MAC address for hash:ip,mac sets too
In commit 8cc4ccf58379 ("ipset: Allow matching on destination MAC address for mac and ipmac sets"), ipset.git commit 1543514c46a7, I removed the KADT check that prevents matching on destination MAC addresses for hash:mac sets, but forgot to remove the same check for hash:ip,mac set. Drop this check: functionality is now commented in man pages and there's no reason to restrict to source MAC address matching anymore.
