avcodec/vc1: change to using v->block instead of s->block for P frames 

The new overlap smooting filter smoothes image pixels stored in v->block.
Switch to v->block instead of s->block for storing decoded image pixels for P
frames. Additionally, we must take incrementing *_blk_idx out of the
vc1_put_signed_blocks_clamped function.
