IP allocation was initially deffered due to lack of binding information. On port update with both `mac_address` and `binding_host_id`` in the request, 'fixed_ips: []' was appended to the new_port data. This caused the check for fixed_ips_requested to return True, which in turn cause deferred_ip_allocation to evaluates False. Only set the new_port default fixed_ips to original_ips if the original port had fixed_ips.
