geoip: Don't NULL-terminate download buffer
The end of the buffer might already contain part of the data payload. Setting the last byte to 0 will thus corrupt the gz file, leading to failed decompression (or previously, to invalid GeoIP database files). The NULL-termination is not necessary in this case, so just omit it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
