ipv6: cleanup: remove unneeded null check

We dereference "sk" unconditionally elsewhere in the function.  

This was left over from:  b30bd282 "ip6_xmit: remove unnecessary NULL
ptr check".  According to that commit message, "the sk argument to 
ip6_xmit is never NULL nowadays since the skb->priority assigment 
expects a valid socket."
