 Description   

The mysql_stmt_reset() api call should reset a statement on server and client side and set the statement state to prepared.
If the statement wasn't prepared before (or the a previous prepare failed), mysql_stmt_reset() will send an unnecessary COM_STMT_CLOSE command with stmt id=0 to the server.

for information for maxscale, this correct an issue that would result in an error : "Unknown prepared statement handler (0) given to MaxScale"
