[RFC PATCH 4/4] hugetlb: remove CONFIG_SYSFS dependency

[Nishanth Aravamudan <nacc@us.ibm.com>]

I incorrectly made the hugetlb kobject functionality depend on SYSFS,
when, in fact, the kobject functions fully work even with out sysfs.
Without sysfs, there is no interface to manipulate the attributes of the
various hugetlb kobjects, but they still exist.
