Cover protocol error: COM_STMT_SEND_LONG_DATA was designed to be quick and not
sent response packets. According to documentation the only way to get an error
is to have out-of-memory on the server-side. However, that's not true, as if
max_allowed_packet_size is smaller than the chunk being sent to the server, the
latter will complain with an error message. However, normally we don't expect
an error message, thus we continue. When sending the next command, which expects
response we will read the unexpected data and error message will look weird.
Therefore we do non-blocking read to clean the line, if there is a need.
Nevertheless, there is a built-in protection when sending a command packet, that
checks if the line is clear - useful for debug purposes and to be switched off
in release builds.
Maybe we can make it automatic by checking what's the value of
max_allowed_packet_size on the server and resending the data.
