    While doing motion search on a macroblock, we usually call
    vp8_find_near_mvs once per reference frame. Actually, for
    different reference frames, the only difference in calculating
    these near_mvs is they may have different sign_bias, which
    causes a sign change in resulting near_mvs. In this change, we
    only do find_near_mvs for the first reference frame. For other
    reference frames, only need to adjust the near_mvs according to
    that reference frame's sign_bias value.
