tcp: Do not reload skb pointer after skb_gro_receive().

This is not necessary.  skb_gro_receive() will never change what
'head' points to.

In it's original implementation (see commit 71d93b39e52e ("net: Add
skb_gro_receive")), it did:

====================
+ *head = nskb;
+ nskb->next = p->next;
+ p->next = NULL;
====================

This sequence was removed in commit 58025e46ea2d ("net: gro: remove
obsolete code from skb_gro_receive()")
