mm/mm_init: remove set_pageblock_order() call from sparse_init()

Browse Source 
free_area_init() already sets pageblock_order before sparse_init() runs
for CONFIG_HUGETLB_PAGE_SIZE_VARIABLE, so sparse_init() does not need to
call set_pageblock_order() again.

With that call removed, set_pageblock_order() is only used in
mm/mm_init.c.  Make it static.
