[IA64] fix show_mem for VIRTUAL_MEM_MAP+FLATMEM
contig.c (FLATMEM) requires the same optimization as in discontig.c for show_mem when VIRTUAL_MEM_MAP is in use. Otherwise FLATMEM has softlockup timeouts. This was boot tested for memory configuration: SPARSEMEM, DISCONTIG+VIRTUAL_MEM_MAP, FLATMEM, FLATMEM+VIRTUAL_MEM_MAP and FLATMEM+VIRTUAL_MEM_MAP with largest memory gap less than LARGE_GAP by using boot parameter "mem=". This was boot tested and "echo m >/proc/sysrq-trigger" output evaluated for : FLATMEM, FLATMEM+VIRTUAL_MEM_MAP, DISCONTIGMEM+VIRTUAL_MEM_MAP and SPARSEMEM.
