In my opinion the initiator should work with the response and call the
done callback of this SCSI command.
This is the way we implement it in SRP: When we get a response for the task 
we set a bit indicting that this command was done. 
In the code that sends the task management and waits for response, we check 
after getting the response if this flag is set. If the flag is set we call 
the done callback. If it is not set, we set the result of the command to 
DID_ABORT.
