Bug 8170 - Loadbalancing nexthop group not updated after VM deletion

Issue:

When the last nexthop present in a DPN is deleted, the loadbalancing next
hop group is not updated. The group still contains the bucket pointing to
the deleted nexthop.

Fix:

There was an error while retrieving the endpointIpaddress for the DPN in
method getEndpointIpAddressForDPN. There was an error in converting the
IpAddress object to string. Appropriate conversion is used now.
