While device_shutdown() walks through devices_kset to shutdown all
devices, device unplug events may race to shutdown individual devices.
Specifically, sd_shutdown(), on behalf of fc_starget_delete(), has
been observed deleting devices during device_shutdown()'s list
traversal. So we factor out list_for_each_entry_safe_reverse(...) in
favor of while (!list_empty(...)).
