ENGR00290659 IPUv3: Fix a flashing vert. line when downsizing 1080i to 300x400.

When split mode deinterlacing is the ipu_calc_stripes_sizes() was failing due
to an unnecessary test. Added logic to use the maximal_stripe_width only if
the flag parameter has the bit 0 clear for not equal stripe sizes.
