Let's do it just like mprotect write-upgrade or during NUMA-hinting faults
on PROT_NONE PTEs: detect if the PTE can be writable by using
can_change_pte_writable().
Set the PTE only dirty if the folio is dirty: we might not necessarily
have a write access, and setting the PTE writable doesn't require setting
the PTE dirty.
