LOAD DATA INFILE is mistaken for LOAD DATA LOCAL INFILE

The response to a LOAD DATA INFILE is just a normal OK packet whereas the response to a LOAD DATA LOCAL INFILE is a Local Infile Request packet. The parsing done by the query classifier does not distinct between the two which causes problems due to the fact that a LOAD DATA LOCAL INFILE puts the readwritesplit into a special mode.

The solution is to distinct the two types of queries and only go into the special mode when LOAD DATA LOCAL INFILE is performed.
