We don't check for NULL consistently in __xfrm6_output().  If "x" were
NULL here it would lead to an OOPs later.  I asked Steffen Klassert
about this and he suggested that we remove the NULL check.

x can't be null here. It would be a bug if __xfrm6_output() is called
without a xfrm_state attached to the skb. I think we can just remove
this null check.
