attach specific router port failure

[Bo Lin]

Steps to reproduce ;

From openstack horizon UI :

1) Create a network
2) Create a router
3)Try to Attach an interface to router with ipaddress

Adding an interface to router with specifying an ip address from openstack horizon , fails with unexpected error

[Bo Lin (linb)]

For fixing the problem, we need to add another condition determination: if no device_owner assigned on port, we would prefer no any attachemnt on the backend port.

    Fix attach specific router port failure

    When specifying a port as a router intf port, we need to ensure no any
    attachment on the port, otherwise backend would report unexpected
    errors. The patch fix the bug by setting attachment_type None if
    no device_owner assigned when creating a port.
