mm/vmalloc: revert "mm/vmalloc.c: check VM_UNINITIALIZED flag in s_show instead of show_numa_info"

The VM_UNINITIALIZED/VM_UNLIST flag introduced by f5252e00 ("mm:
avoid null pointer access in vm_struct via /proc/vmallocinfo") is used to
avoid accessing the pages field with unallocated page when
show_numa_info() is called.  This patch move the check just before
show_numa_info in order that some messages still can be dumped via
/proc/vmallocinfo.  This patch revert commit d157a558 ("mm/vmalloc.c: check
VM_UNINITIALIZED flag in s_show instead of show_numa_info");
