scsi: core: Don't wait for quiesce in scsi_stop_queue()
scsi_stop_queue() has just two callers, one with and one without
"nowait". As blk_mq_quiesce_queue() comes down to
blk_mq_quiesce_queue_nowait() followed by blk_mq_wait_quiesce_done(), we
might as well open-code this in scsi_device_block().
Also, add a comment explaining why blk_mq_quiesce_queue_nowait() must be
called with the state_mutex held, see
