Commit id '3c12b654' took a "large hammer" approach to inhibiting logins which causes issues if there are iSCSI targets not being managed by libvirt. Now that the previous commit ensures that the iscsi initiator doesn't update the /var/lib/iscsi tree with the results for a 'sendtargets' by using the "--op nonpersistent" option, let's remove the code from virISCSIScanTargets that disables autologin for every target, but add that same setting into the start pool code for each managed/started target to ensure that nothing else goes and tries to autologin.
