smbd: return correct error for compound related requests that went async

Browse Source 
For a compound related request chain of eg CREATE+NOTIFY+GETINFO, the NOTIFY
will typically go async. When this is noted in smbd_smb2_request_pending_queue()
the pending async tevent_req is cancelled which means we return
NT_STATUS_CANCELLED to the client while Windows returns
NT_STATUS_INTERNAL_ERROR.
