During reboot/shutdown cycle, the active sessions were not updated.
In iSCSI Boot case, the boot session was alive and this fix informs
that the machine is going down, so no more ops happens on that session.

I am not sure how this is working or what it fixes. During
shutdown/reboot when the pci_driver shutdown callback is called, without
the patch what is happening? Does the host shutdown cause iscsid to try
and recover the session and that causes a shutdown/reboot hang?
I think you want to use ISCSI_ERR_INVALID_HOST. That would cause a clean
shutdown of the sessions if iscsid is still up at that time. This would
cause ep_disconnect to get called and a logout pdu to get sent.
ISCSI_ERR_CONN_FAILED just causes recovery to start (ep_disconnect will
run if the ep is up and we will try to reconnect).
