libcli/smb: list NT_STATUS_FILE_CLOSED as expected ioctl response.
Some IOCTL requests change the behavior with new protocol versions.
E.g. FSCTL_VALIDATE_NEGOTIATE_INFO resulted in NT_STATUS_FILE_CLOSED
for old servers.
As SMB2 signing might be skipped for responses with NT_STATUS_FILE_CLOSED
we need to list it explicitly in the expected return values.
This way we'll get NT_STATUS_ACCESS_DENIED, if the server doesn't
sign the response to a signed requests.
