Commit7cbbf9f1fa("ixgbe: fix xdp handle calculations") reintroduced the addition of the umem headroom to the xdp handle in the ixgbe_zca_free, ixgbe_alloc_buffer_slow_zc and ixgbe_alloc_buffer_zc functions. However, the headroom is already added to the handle in the function ixgbe_run_xdp_zc. This commit removes the latter addition and fixes the case where the headroom is non-zero.

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.
