  If neither of the flags to round down (V4L2_SEL_FLAG_LE) or round up
(V4L2_SEL_FLAG_GE) are specified by the user, then round to nearest
multiple of requested value while updating the crop rectangle coordinates.

Use the rounding macro which gives preference to rounding down in case two
nearest values (high and low) are possible to raise the probability of
cropping rectangle falling inside the bound region.
