V4L/DVB (12119): pvrusb2: Re-fix hardware scaling on video standard change
The cx25840 module's VBI initialization logic uses the current video standard as part of its internal algorithm. This therefore means that we probably need to make sure that the correct video standard has been set before initializing VBI. (Normally we would not care about VBI, but as described in an earlier changeset, VBI must be initialized correctly on the cx25840 in order for the chip's hardware scaler to operate correctly.) It's kind of messy to force the video standard to be set before initializing VBI (mainly because we can't know what the app really wants that early in the initialization process). So this patch does the next best thing: VBI is re-initialized after any point where the video standard has been set.
