Actually, hugetlb_register_node() also called, via a function pointer
that hugetlb registers with the sysfs node driver, when a node is hot
plugged.  So, I think the correct approach is to remove the '__init'
from hugetlb_sysfs_add_hstate() as this is also used at runtime.  I
missed this in the original submittal.
