netlink: don't orphan skb in netlink_trim()
Netlink doesn't account skbs to the sending socket, so the there's no
need to orphan the skb before trimming it.
Removing the skb_orphan() call is required for mmap'ed netlink, which uses
a netlink specific skb destructor that must not be invoked before the
final freeing of the skb.
