Revert ncsi: Propagate carrier gain/loss events to the NCSI controller

commit 9e2e7efbbb upstream.

This reverts commit 3780bb2931.

The cited commit introduced unwanted behavior.

The intent for the commit was to be able to detect carrier loss/gain
for just the NIC connected to the BMC. The unwanted effect is a
carrier loss for auxiliary paths also causes the BMC to lose
carrier. The BMC never regains carrier despite the secondary NIC
regaining a link.

This change, when merged, needs to be backported to stable kernels.
5.4-stable, 5.10-stable, 5.15-stable, 6.1-stable, 6.5-stable
