Fix test_b010 parameter count
As stated by the scmi testlist documentation, test_b010 is testing for an invalid command by first issuing it, and then by verifying the return status code from the PROTOCOL_MESSAGE_ATTRIBUTES command.
https://github.com/ARM-software/scmi-tests/blob/master/docs/scmi_testlist.md
The PROTOCOL_MESSAGE_ATTRIBUTES requires the message_id to be forwarded as an argument, hence the num_parameter in the val_send_message should be set to 1 to make sure the message is constructed with the appropriate length.
