powerpc/ptdump: Fix walk_vmemmap() to also print first vmemmap entry
Currently walk_vmemmap() skips the first vmemmap entry pointed to by
vmemmap_list pointer itself. Fix that.
With the fix applied the vmemmap entry at 0xc00c000000000000 for hash is
displayed:
$ cat /sys/kernel/debug/kernel_hash_pagetable
...
0xc00c000000010000: AVPN:cd7bd4e0000 ssize: 1T ...
0xc00c000000000000: AVPN:cd7bd4e0000 ssize: 1T ...
