f2fs: do in batches truncation in truncate_hole truncate_data_blocks_range can do in batches truncation which makes all changes in dnode page content, dnode page status, extent cache, block count updating together. But previously, truncate_hole() always truncates one block in dnode page at a time by invoking truncate_data_blocks_range(,1), which make thing slow. This patch changes truncate_hole() to do in batches truncation for all target blocks in one direct node inside truncate_data_blocks_range, which can make our punch hole operation in ->fallocate more efficent.
