[PATCH] staging: vt6656: Fix possible leak in vnt_download_firmware()

[Christian Engelmayer]

When failing to allocate buffer memory, function vnt_download_firmware() goes
through the wrong exit path and fails to release the already requested
firmware. Thus use the correct cleanup. Detected by Coverity CID 1269128.
