Summary

Extend the optional ICE failure-injection facility with points for the
MAC anti-spoof firmware update and each mandatory VF reset stage.

The reset points report a failed Tx drain command, VFR timeout, receive
queue disable, or final PCIe transaction drain after the corresponding
hardware operation.  This permits fail-closed state and recovery tests
without deliberately leaving live DMA during teardown.

The points remain absent unless the kernel is built with
options DRIVER_FAILPOINTS and retain the existing PF and VF selectors.

Thanks a lot for all your fixes. I'm building an image for our validation team to run some regression tests. I'll get back to you as soon as I get any feedback.
