Delete interface operation on distributed router fails

[Igor Zinovik]

Affected version:
NSX Version: 6.1.4, Build: 2691049
Neutron NSX plugin 2015.1.2 (package is built using git tag 2015.1.2)

Scenario:
a) create "EXTERNAL_NET"
b) create tenant network "INTERNAL_NET" with enabled DHCP
c) create distributed router "DVR" and set gateway as "EXTERNAL_NET"
d) add interface to "DVR" in "INTERNAL_NET"
e) wait 10-15 seconds to allow VMs reconfiguration complete
f) delete gateway on "DVR"
g) delete remaining interface on "DVR"

Expected result:
 interface successfully removed
Actual result:
 error is reported

CLI commands scenario:
$ neutron net-create EXTERNAL --router:external --shared
$ neutron subnet-create --allocation-pool start=172.16.211.100,end=172.16.211.150 --gateway 172.16.211.1 --disable-dhcp EXTERNAL 172.16.211.0/24

$ neutron net-create INTERNAL_NET
$ neutron subnet-create INTERNAL_NET --name INTERNAL_NET-subnet 192.168.0.0/24

$ neutron router-create DVR --distributed True
$ neutron router-interface-add DVR INTERNAL_NET-subnet
$ neutron router-gateway-set DVR EXTERNAL
$ sleep 60 # wait for NSX edge VM provisioning
$ neutron router-gateway-clear DVR
$ neutron router-interface-delete DVR INTERNAL_NET-subnet

This is resolved with NSX 6.2
