block: don't verify IO lock for freeze/unfreeze in elevator_init_mq()
commit 357e1b7f730bd85a383e7afa75a3caba329c5707 upstream.
elevator_init_mq() is only called at the entry of add_disk_fwnode() when
disk IO isn't allowed yet.
So not verify io lock(q->io_lockdep_map) for freeze & unfreeze in
elevator_init_mq().
