mm: meminit: inline some helper functions
early_pfn_in_nid() and meminit_pfn_in_nid() are small functions that are
unnecessarily visible outside memory initialisation. As well as
unnecessary visibility, it's unnecessary function call overhead when
initialising pages. This patch moves the helpers inline.
