Only reset dns_name when unbinding port if DNS is integrated

Browse Source 
We only set the dns_name on the port if the "DNS Integration"
extension is enabled, so we should only reset it on the port
when unbinding if the extension is enabled, otherwise some
Neutron stadium plugins will fail since they don't expect
the 'dns_name' attribute to be on the port.
