mm/page_ext: remove rollback for untouched mem_section in online_page_ext
If init_section_page_ext failed, we only need rollback for mem_section
before failed mem_section. Make rollback end point to failed mem_section
to remove unnecessary rollback.
As pfn += PAGES_PER_SECTION will be executed even if init_section_page_ext
failed. So pfn points to mem_section after failed mem_section. Subtract
one mem_section from pfn to get failed mem_section.
