Nicolas Dichtel 06d3f43d52 netlink: avoid a double skb free in genlmsg_mcast() 
[ Upstream commit 02a2385f37 ]

nlmsg_multicast() consumes always the skb, thus the original skb must be
freed only when this function is called with a clone.

Fixes: cb9f7a9a5c ("netlink: ensure to loop over all netns in genlmsg_multicast_allns()")
