Fix c vs avx mismatch of diamond_search_sad()
In the function vp9_diamond_search_sad_avx(), arranged
the cost vector in a specific order. This ensures that
the motion vector with the least index is selected,
when there exists more than one candidate motion
vector with the minimum cost, thus resolving the
c vs avx mismatch.
