Modify disk_update_zone_resources() to freeze the device queue before updating the number of zones, zone capacity and other zone related resources. The locking order resulting from the call to queue_limits_commit_update_frozen() is preserved, that is, the queue limits lock is first taken by calling queue_limits_start_update() before freezing the queue, and the queue is unfrozen after executing queue_limits_commit_update(), which replaces the call to queue_limits_commit_update_frozen().This change ensures that there are no in-flights I/Os when the zone resources are updated due to a zone revalidation.
