    Windows: Fail RX_INVALID_OPERATION errors
    
    RX_INVALID_OPERATION errors were not resulting in an eventual
    failure and the RPC was being repeated indefinitely.  There were
    three subtle problems:
    
     1. RX_INVALID_OPERATION was being processed by cm_Analyze()
        resulting in a retry in all cases.  Even those where no
        connp was passed in as NULL.  connp == NULL implies that
        no server could be obtained so the RPC was not issued on
        this pass.  As a result there should be no retry.
    
     2. RX_INVALID_OPERATION was mapped to CM_ERROR_UNKNOWN which
        is not an error that is reported to the AFS redirector.
    
     3. RDR_BkgFetch was setting CM_REQ_NORETRY and permitting
        the retries to be handled by the cm_daemon threads.  However,
        CM_ERROR_UNKNOWN was not treated as a fatal error by cm_Daemon.
    
    Address the failures in the following ways:
    
     A. cm_Analyze no longer retries calls which did not take place.
    
     B. Create a new CM_ERROR_INVAL_NET_RESP error for RX_INVALID_OPERATION
        which is translated to the Win32 STATUS_INVALID_NETWORK_RESPONSE
        error.  This is now returned to the AFS redirector and treated
        as a fatal error.
    
     C. RDR_BkgFetch no longer queues tasks to cm_Daemon with the
        CM_REQ_NORETRY flag set.
