x86-64: fix combining of regions in init_memory_mapping()
When nr_range gets decremented, the same slot must be considered for
coalescing with its new successor again.
The issue is apparently pretty benign to native code, but surfaces as a
boot time crash in our forward ported Xen tree (where the page table
setup overall works differently than in native).
