memory hotadd 6/7: Allocate L3 table for whole direct maping range if
memory hotplug is supported.

Hot-added memory may need a new L4 entry for 1:1 mapping. This patch
setup all L4 entry for 1:1 mapping if memory hotadd is needed, so that
we don't need sync the guest page table in page fault handler.
