mm: mlock: update the interface to use folios

Browse Source 
Update the mlock interface to accept folios rather than pages, bringing
the interface in line with the internal implementation.

munlock_vma_page() still requires a page_folio() conversion, however this
is consistent with the existent mlock_vma_page() implementation and a
product of rmap still dealing in pages rather than folios.
