block: don't protect generic_make_request_checks with blk_queue_enter
Now a063057d ("block: Fix a race between request queue removal and the block cgroup controller") has been reverted, and blkcg_exit_queue() won't be called in blk_cleanup_queue() any more. So don't need to protect generic_make_request_checks() with blk_queue_enter(), then the total mess can be cleaned. 37f9579f ("blk-mq: Avoid that submitting a bio concurrently with device removal triggers a crash") is reverted.
