igb: fix link test skipping when interface is admin down
The igb driver incorrectly skips the link test when the network
interface is admin down (if_running == false), causing the test to
always report PASS regardless of the actual physical link state.
This behavior is inconsistent with other drivers (e.g. i40e, ice, ixgbe,
etc.) which correctly test the physical link state regardless of admin
state.
Remove the if_running check to ensure link test always reflects the
physical link state.
