For non-rd pickmode: remove VAR_PARTITION condition.

Keep the logic, transform size based on cyclic refresh and bsize,
(that was conditioned on VAR_PARTITION conditions) the same
for all speeds in non-rd mode (speeds >= 5).

No change to speeds >=6.
Small improvement for speed 5, ~0.5/1.5% gain for avg psnr/ssim.
