[RFC PATCH 7/9] mm/migrate: rename rmap_walk_arg folio

[Huan Yang]

The current naming of "folio" in rmap_walk_arg does not clearly reflect
the actual role of this parameter. This patch renames it to "src" to
distinguish it from the "folio" parameter in remove_migration_pte.

No functional change.
