fs/proc/vmcore.c: hide vmcoredd_mmap_dumps() for nommu builds
Without CONFIG_MMU, we get a build warning:
fs/proc/vmcore.c:228:12: error: 'vmcoredd_mmap_dumps' defined but not used [-Werror=unused-function]
static int vmcoredd_mmap_dumps(struct vm_area_struct *vma, unsigned long dst,
The function is only referenced from an #ifdef'ed caller, so
this uses the same #ifdef around it.

Fixes: 7efe48df8a3d ("vmcore: append device dumps to vmcore as elf notes")
