Not implemented for a reason. The target has no idea if the CID the
host requested to be aborted is from the same context that the target
has. Target may have previoulsy completed it, and the host re-issued a
new command after the abort, and due to the queueing could have been
observed in a different order, and now you aborted the wrong command.
