datapath-windows: We don't need to keep validation ports in ovs

Validation ports are used internally by the hyper-v switch to validate
and verify settings for the real hyper-v switch ports that will be
connected to the VNic. The validation ports are of no use to us - we
must skip handling them, and return STATUS_SUCCESS as the OID result.
