Hans Verkuil 5fd3269dfa media: vivid: fix wrong pixel_array control size 
commit 3e43442d49 upstream.

The pixel_array control size was calculated incorrectly:
the dimensions were swapped (dims[0] should be the height), and the
values should be the width or height divided by PIXEL_ARRAY_DIV
and rounded up. So don't use roundup, but use DIV_ROUND_UP instead.

This bug is harmless in the sense that nothing will break, except that
it consumes way too much memory for this control.
