mm/hugetlb: move hugetlb_sysfs_initialized into hugetlb_register_all_nodes()

Browse Source 
hugetlb_sysfs_init() guards the "hugetlb_sysfs_initialized = true"
assignment with an #ifdef CONFIG_NUMA block, while the following
hugetlb_register_all_nodes() call is left unguarded and relies on the
empty !CONFIG_NUMA stub.

Move the assignment into the NUMA version of hugetlb_register_all_nodes(),
before it registers the online nodes, so the #ifdef in
hugetlb_sysfs_init() can go away.  Keep the !CONFIG_NUMA stub, so the call
site is unconditional in both configurations.

No functional change; this is an #ifdef cleanup.
