mm: renovate page_address_in_vma()
This function doesn't modify any of its arguments, so if we make a few
other functions take const pointers, we can make page_address_in_vma()
take const pointers too. All of its callers have the containing folio
already, so pass that in as an argument instead of recalculating it. Also
add kernel-doc
