Small improvement in sub-pixel motion search If the current best mv(namely, the search center) is still the best mv after the first level search, the second level checks is skipped. This patch doesn't change the bitstream. At speed 0, it speeds up the encoder by 1% - 2%. Change-Id: I054c91b884d3f7aef157436c061744562bd6506d
