We now use smbXcli_conn_is_connected() and
dcerpc_binding_handle_is_connected() to verify only the dcerpc layer
got an error. The expected error is EIO mapped to NT_STATUS_IO_DEVICE_ERROR.
NT_STATUS_INVALID_HANDLE should only be visible at the SMB layer,
but we keep this as allowed return value for now, until
the dcerpc layer is fixed.
