====================
ipv6: addrlabel: avoid dirtying ip6addrlbl_entry

The refcount on ip6addrlbl_entry is only used to make sure ip6addrlbl_entry
does not disappear while ip6addrlbl_get() is allocating an skb.

We can instead allocate skb first, then use RCU, so that we no longer need
to refcount these structures.
