powerpc/ptdump: Fix addresses display on PPC32
Commit 453d87f6a8ae ("powerpc/mm: Warn if W+X pages found on boot") wrongly changed KERN_VIRT_START from 0 to PAGE_OFFSET, leading to a shift in the displayed addresses. Lets revert that change to resync walk_pagetables()'s addr val and pgd_t pointer for PPC32.
