[ Upstream commit c31e76bcc379182fe67a82c618493b7b8868c672 ]
Commit 97889f9ac24f8 ("blk-mq: remove synchronize_rcu() from blk_mq_del_queue_tag_set()") remove handle of TAG_SHARED in restart, then shared_hctx_restart counted for how many hardware queues are marked for restart is removed too. Remove the stale comment that we still count hardware queues need restart.
