If we are only about to clear a hardware pte entry, then pte makeup code is

Changes for V2:
- Use "1f" instead of "set_pte" as label
- Build/bootup test with thumb mode
- checkpatch script shows:
total: 0 errors, 0 warnings, 44 lines checked
./0001-Skip-unnecessary-pte-makeup-when-clearing-it.patch has no obvious style problems and is ready for submission.
