Jingning Han 9fb1d69e82 Use the actual transform block size for loop filter selection 
Parse the recursive transform block partition to fetch the actual
transform size. Use this correct transform size to select the
corresponding loop filter kernel. This slightly improves the coding
performance of recursive transform partition for hdres to 0.14%.
