Ming Lei 737f98cfe7 blk-mq: initialize mq kobjects in blk_mq_init_allocated_queue() ...

Both q->mq_kobj and sw queues' kobjects should have been initialized
once, instead of doing that each add_disk context.

Also this patch removes clearing of ctx in blk_mq_init_cpu_queues()
because percpu allocator fills zero to allocated variable.

This patch fixes one issue[1] reported from Omar.
