David Miller 6892286e9c 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 71d93b39e5 ("net: Add
skb_gro_receive")), it did:

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

This sequence was removed in commit 58025e46ea ("net: gro: remove
obsolete code from skb_gro_receive()")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
