From: Kieran Bingham <kieran.bingham@ideasonboard.com>

commit 360a3a90c6261fe24a959ff38f8f6c3a8468f23c upstream.

The frame counters are inadvertently counting packets with content as
empty.

Fix it by correcting the logic expression

Fixes: 7bc5edb00bbd [media] uvcvideo: Extract video stream statistics
