Revert "genetlink: disallow subscribing to unknown mcast groups"
Commit 5ad6300524c0332 ("genetlink: disallow subscribing to unknown
mcast groups") disallows userspace to subscribe to groups that don't
exist in kernel. As a result, communication between processes is
not possible unless they explicitly register a dummy group with the
kernel even if the communication is between userspace processes
only. NETLINK_USERSOCK cannot be used here since userspace processes
would require CAP_NET_ADMIN to receive multicast messages which
is available for priveleged processes only.
Fix this problem by reverting the change till a solution is
determined internally and upstream discussion.
