Kolla-ansible uses the variable 'ironic_dnsmasq_interface' to denote the
interface for the ironic inspector dnsmasq service. Previously kayobe
was incorrectly using the variable 'inspector_dnsmasq_interface', which
caused kolla-ansible to ignore it and use the API interface instead.
This patch fixes that.
