RHEL8.6 booting over iscsi can enter a loop forever in dracut-initqueue if one netroot path is lost.

Issue

• If during a boot one of multiple netroot paths are lost and generate a hard error ie "No route to host" iscsiadm running under dracut-initqueue enters a persistent loop trying to login to the down link.
