This reverts commit f51f0998e1.
This causes datarate tests to fail. Some are due to the new default
keyframe distance, another causes an assert even forcing 9999:
[ RUN ] VP9/DatarateOnePassCbrSvc.OnePassCbrSvc3SpatialLayers/0
test_libvpx:
vpx_dsp/x86/vpx_subpixel_8t_intrin_ssse3.c:853: scaledconvolve2d:
Assertion `y_step_q4 <= 32' failed.
