s4:libcli/smb2: ignore SMB2_OP_CANCEL responses
If there're a problem with signing or the session doesn't exists
any more the server responses with a failure, instead of not
sending a response.
For now we ignore the reponse, as there's not much we could do with it
and it's not likely that we generate bad requests, which trigger
that behavior, except for testing.
