kobj: fix threshold_init_device/kobject_uevent_env oops
the logic in this function is just crazy. It's recursive, but we can circumvent the creation for the kobject and whole creation of the threshold_block if some conditions are met. That's why we see the allocate_threshold_blocks so many times in the callstack, yet only a few kobjects created. Then we blow up in kobject_uevent_env() on the first debug printk. Which means that we are just passing in garbage. Man, this is one time that comments in code would have been very nice to have, and why forward goto's into major code blocks are just evil...
