[PATCH] hugetlb: fix sparse warning for hugetlb_register_node

[Claudiu Ghioc]

Removed the following sparse warnings:
*  mm/hugetlb.c:1764:6: warning: symbol
    'hugetlb_unregister_node' was not declared.
    Should it be static?
*   mm/hugetlb.c:1808:6: warning: symbol
    'hugetlb_register_node' was not declared.
    Should it be static?

Hi Jiri,

Can you pick this up via trivial tree?

Seems like sparse is correct here, as register_hugetlbfs_with_node is 
passing pointers to those functions.

Will take it.
