mm/khugepaged: use ALIGN helpers for PMD alignment

Browse source

PMD alignment in khugepaged is currently implemented using a mix of
rounding helpers and open-coded bitmask operations.

Use ALIGN() and ALIGN_DOWN() consistently for PMD-sized address range
alignment, matching the preferred style for address and size handling.

No functional change intended.
