Fix: Error while reading from USB endpoint 

This patch fixes the bug reported here:

http://sourceforge.net/mailarchive/message.php?msg_id=28350157


When using Rlink under Linux, openocd exits with:

"Error: Read of endpoint 2 returned -75, expected 17"

The return value of -75 translates into EOVERFLOW. The cause is a wrong output buffer size argument passed to dtc_run_download().
