Fix warning "WARN_ON_ONCE(!async && in_interrupt())" that occurs during SCSI device scanning when blk_freeze_queue_start() calls blk_mq_run_hw_queues() synchronously from interrupt context.

Can you show the whole stack trace in the warning? The in-code doesn't indicate that freeze queue can be called from scsi's interrupt context.

Thanks, Ming
