net/mlx5e: Fix use-after-free after xdp_return_frame
[ Upstream commit 12fc512f5741443a03adde2ead20724da8ad550a ]
xdp_return_frame releases the frame. It leads to releasing the page, so
it's not allowed to access xdpi.xdpf->len after that, because xdpi.xdpf
is at xdp->data_hard_start after convert_to_xdp_frame. This patch moves
the memory access to precede the return of the frame.
