ivtv - Fix potential race condition in yuv handler
From: Ian Armstrong <ian@iarmst.demon.co.uk>
Modified yuv register update handling to remove a potential race condition
which could occur with the first video frame.
Also removed a forced yuv position update, since changing the source video
dimensions or interlace settings doesn't affect the frame already being
displayed.
Priority: normal
