When receiving the ccb abort message (D2ND_ABORT_CCB) over fevs, IMMND will
abort the message and send response to client if it's the originating node. See
immnd_evt_proc_ccb_finalize().
In some cases the client is not in a sync call (i.e. not waiting for response)
but IMMND still sends that response to the client. One example is when the OI
attaches/deattaches. That may cause the client to receive unexpected response
if the client at that time calls an sync IMM api.
Details of the problem is explained here
