Routine Description:
Called when the Cluster Network driver is unloading. Frees all resources
allocated by the Cluster Transport.
The Transport is guaranteed not to receive any more user-mode requests,
membership send requests, or membership events at the time
this routine is called.
A shutdown of the Cluster Network driver has already occured when this
routine is called.
Arguments:
None.
Return Value:
None
Notes:
This routine MUST be callable even if CxLoad() has not yet been
called.
