Revert "vp9: Speed feature to adapt partition based on source_sad."

This reverts commit 064fc570ff8399536563e3846500fd99b273b034.

This causes an assertion failure in vp9_mcomp.c when running
gtest_filter=VP9/MotionVectorTestLarge.OverallTest/41:
`mv->col >= -((1 << (11 + 1 + 2)) - 1) && mv->col < ((1 << (11 + 1 + 2))
- 1)'
