[Bug]: "CSV using LOAD DATA" import with charset selection results in "This plugin does not support compressed imports!"

Describe the bug

If you select any charset other than utf8 for importing "CSV using LOAD DATA" an error message is shown: "This plugin does not support compressed imports!"

If I understand correctly, this is due to the condition here: https://github.com/phpmyadmin/phpmyadmin/blob/RELEASE_5_2_3/libraries/classes/Plugins/Import/ImportLdi.php#L103 since $charset_conversion is not False, the error is thrown.

How to Reproduce

1. Go to database table
2. Click "Import"
3. Select CSV file
4. Select any charset, other than utf8
5. Under Format, select "CSV using LOAD DATA"
6. Click "Import"
7. An error is displayed: "This plugin does not support compressed imports!"

Expected behavior

I expected the data to be imported with the correct character set. I was able to add $sql .= ' CHARACTER SET latin1 '; to the code to force it to use latin1 and it worked.
