Intel Wired LAN Driver Updates 2021-10-06

This series contains updates to i40e and iavf drivers.

Jiri Benc expands an error check to prevent infinite loop for i40e.

Sylwester prevents freeing of uninitialized IRQ vector to resolve a
kernel oops for i40e.

Stefan Assmann fixes a double mutex unlock for iavf.
