 Routine Description:

 This routine patches the RDBSS created srv call instance with the information required
 by the mini redirector.

 Arguments:

 RxContext        - Supplies the context of the original create/ioctl

 CallBackContext  - the call back context in RDBSS for continuation.

 Return Value:

 RXSTATUS - The return status for the operation
