Bugfix for encoder reported PSNR for superres.

Earlier, encoder PSNR computation was incorrectly comparing scaled
source with upscaled encoded frame, so values reported by "--psnr" were
incorrect when superres was being used.

We change the logic of when scaling is required to correct this problem.

Note: only affects output of "--psnr"; no change in encoding output.
