- Abort an asynchronous transmit or receive request.

- The Cancel() function is used to abort a pending transmit or receive request.
- If the token is in the transmit or receive request queues, after calling this
- function, Token->Status will be set to EFI_ABORTED, and then Token->Event will
- be signaled. If the token is not in one of the queues, which usually means the
- asynchronous operation has completed, this function will not signal the token,
