md: fix mddev->kobj lifetime
Once a kobject is initialized, the containing object should not be
directly freed. So delay initialization until it is added. Also
remove the kobject_del call as the last put will remove the kobject as
well. The explicitly delete isn't needed here, and dropping it will
simplify further fixes.
With this md_free now does not need to check that ->gendisk is non-NULL
as it is always set by the time that kobject_init is called on
mddev->kobj.
