LIO: Don't add ACL for local initiator name

Currently cinder-rtstool requires /etc/iscsi/initiatorname.iscsi
to be present in order to create a LUN/ACL/portal successfully.
However, this is not required since Cinder will create the
required ACLs dynamically at attach time as well.

Removing this path means that iscsi-initiator-utils no longer
needs to be installed locally when using a remote Nova compute
node.
