mm/migrate_device: cleanup up PMD Checks and warnings
Remove the odd VM_WARN_ON_FOLIO(!folio, folio) usage and replace it with a
simpler VM_WARN_ON_ONCE(!folio) check.
Drop the redundant VM_WARN_ON_ONCE(!pmd_none(*pmdp) &&
!is_huge_zero_pmd(*pmdp)).
Refactor the PMD checks, making the control flow clearer and avoiding
duplicate condition checks.
