Add a couple of checks to make sure timestamping is on and that the
timestamp value from DMA is valid. This avoids any functional issues
that could come from a misinterpreted time stamp.
One of the functions changed doesn't need a return value added because
there was no value in checking from the calling locations.
While here, fix a couple of reverse christmas tree issues next to
the code being changed.
Fixes: f56e7bba22fa ("igb: Pull timestamp from fragment before adding it to skb")
Fixes: 9cbc948b5a20 ("igb: add XDP support")

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.
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.
