Public bug reported:

On Windows / Hyper-V Server 2008 R2, when a switch port have to be disconnected because the VM using it was removed,
DisconnectSwitchPort will fail, returning an error code and a HyperVException is raised. If the exception is raised, the switch port is not removed and will make the WMI operations more expensive.

If the VM's VNIC has been removed, disconnecting the switch port is no
longer necessary and it should be removed.
