bttv: Width must be a multiple of 16 when capturing planar formats
commit 5c915c68763889f0183a1cc61c84bb228b60124a upstream.
On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).
This turns out to be caused by max-width (924) not being a multiple of 16.
We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.
