    Speed up recursive transform block partition search. When a txfm
    block is selected as all zero coefficients, skip the search over
    further split partition.
    
    Tested with txk-sel on, this makes the speed 0 / 1 both 10 - 15%
    faster at medium - high target bit-rate range. The coding
    performance change is neutral - 0.011% better for lowres set.
