media: v4l2-dv-timings.c: fix wrong condition in two for-loops
[ Upstream commit 4108b3e6db31acc4c68133290bbcc87d4db905c9 ]
These for-loops should test against v4l2_dv_timings_presets[i].bt.width,
not if i < v4l2_dv_timings_presets[i].bt.width. Luckily nothing ever broke,
since the smallest width is still a lot higher than the total number of
presets, but it is wrong.
The last item in the presets array is all 0, so the for-loop must stop
when it reaches that sentinel.
