Make ext_tile compatible with reference_buffer

In ext_tile experiment, when cm->large_scale_tile is 1, prev_frame_id can be
the same as current_frame_id, which is prohibited in reference_buffer
experiment and causes "CORRUPT_FRAME" error to be reported.

In this patch, enable/disable reference_buffer according to large_scale_tile
value, and thus make these 2 experiments compatible.
