v11:
According to the comments of David, simplify page_to_nid() to pass
&(PF_POISONED_CHECK(page)->flags) directly.

v10:
According to the comments of David, drop the redundant CONFIG_NUMA split
in page_to_nid()/folio_nid() and remove the SECTIONS_WIDTH != 0 guard
around ASSERT_EXCLUSIVE_BITS() in memdesc_section().
