Even though .mq_kobj, ctx->kobj and q->kobj share same lifetime from block layer's view, actually they don't because userspace may grab one kobject anytime via sysfs, so each kobject's lifetime has to be independent, then the objects(mq_kobj, ctx) which hosts its own kobject have to be allocated dynamically. This patch fixes kernel panic issue during booting when DEBUG_KOBJECT_RELEASE is enabled.
