blk-throttle: remove dead field last_check_time from throtl_grp
The last_check_time field in throtl_grp was used by the
CONFIG_BLK_DEV_THROTTLING_LOW mechanism (in throtl_upgrade_check() and
the downgrade logic) to timestamp the last upgrade/downgrade check.
Commit bf20ab538c81 ("blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW")
removed all five of its uses in blk-throttle.c and the surrounding LOW
fields (latency_target, last_finish_time, checked_last_finish_time,
avg_idletime, idletime_threshold, bio_cnt, bad_bio_cnt,
bio_cnt_reset_time), but missed the field definition itself.
It has been a dead field since then: zero references in blk-throttle.c
and the whole tree. Remove it.
