xfrm: Switch to skb_dstref_steal to clear dst_entry

Going forward skb_dst_set will assert that skb dst_entry
is empty during skb_dst_set. skb_dstref_steal is added to reset
existing entry without doing refcnt. Switch to skb_dstref_steal
in __xfrm_route_forward and add a comment on why it's safe
to skip skb_dstref_restore.
