Don't reset mb clamping state during splitmv decoding The MV decoding changes in c5fb0eb introduced a bug where the macroblock clamping state was reset for each partition, so if an earlier partition needed clamping but a subsequent one didn't, the MB wouldn't receive clamping. Instead, the state is only set during splitmv decoding, never cleared. Change-Id: I224fe258493405ee0f6a04596acdb622c475e845
