Docs/mm: fix outdated "radix tree" in page_migration

Browse source

Steps 7 and 9 of the migration description still say "radix tree", unlike
steps 5 and 11 which already use "i_pages lock".  The page cache moved to
the XArray at mapping->i_pages long ago.  Use "page cache tree" for the
two remaining references.
