Remove some cases for turning off arf.
Flipping arf on and off too often is hurting some clips.
This change makes no difference for 50-75% of our test
clips but helps some by a big margin. (eg. std-hd crew
by 6% and one of the YT and YT-hd clips by 14%)
Average improvements for 2 pass, speed 2 (psnr,ssim)
are as follows:-
derf 0.165%, 0.210%
yt 1.210%, 1.464%
yt-hd 1.189%, 1.471%
std-hd 1.031%, 0.886%
