Currently ice_finalize_xdp_rx() is called only when xdp_prog is present
on VSI, which is a good thing. However, this optimization can be
enhanced and check only if any of the XDP_TX/XDP_REDIRECT took place in
current Rx processing. Non-zero value of @xdp_xmit indicates that
xdp_prog is present on VSI. This way XDP_DROP-based workloads will not
suffer from unnecessary calls to external function.
