scsi: core: Don't wait for quiesce in scsi_device_block()
scsi_device_block() is only called from scsi_target_block(), which calls it
repeatedly for every child device. For targets with many devices, waiting
for every queue to quiesce may cause a substantial delay (we measured more
than 100s delay for blocking a FC rport with 2048 LUNs).
Just call blk_mq_wait_quiesce_done() once from scsi_target_block() after
stopping all queues.
