block/blk-throttle: drop unneeded blk_stat_enable_accounting

Browse Source 
After the removal of CONFIG_BLK_DEV_THROTTLING_LOW, it is no longer
necessary to enable block accounting, so remove the call to
blk_stat_enable_accounting(). With that, the track_bio_latency variable
is no longer used and can be deleted from struct throtl_data. Also,
including blk-stat.h is no longer necessary.
