> Commit 4c5d9a7fa149 ("i40e: fix xdp handle calculations") reintroduced the
> addition of the umem headroom to the xdp handle in the i40e_zca_free,
> i40e_alloc_buffer_slow_zc and i40e_alloc_buffer_zc functions. However, the
> headroom is already added to the handle in the function i40_run_xdp_zc.
> This commit removes the latter addition and fixes the case where the
> headroom is non-zero.
