x86/dump_pagetables: Fix LDT remap address marker

The LDT remap placement has been changed. It's now placed before the direct
mapping in the kernel virtual address space for both paging modes.

Change address markers order accordingly.

Fixes: d52888aa2753 ("x86/mm: Move LDT remap out of KASLR region on 5-level paging")
