The PPN field in a non-leaf PDT entry is positioned differently from that
in a leaf PDT entry. The original implementation incorrectly used the leaf
entry's PPN mask to extract the PPN from a non-leaf entry, leading to an
erroneous page table walk.
This commit introduces new macros to properly define the fields for
non-leaf PDT entries and corrects the page table walk.
