mm: mempolicy: skip non-migratable VMAs when setting MPOL_MF_LAZY

MPOL_MF_LAZY is not visible from userspace since a720094ded8c ("mm:
mempolicy: Hide MPOL_NOOP and MPOL_MF_LAZY from userspace for now"), but
it should still skip non-migratable VMAs such as VM_IO, VM_PFNMAP, and
VM_HUGETLB VMAs, and avoid useless overhead of minor faults.
