mm, sparse: complain about implicit altmap usage in vmemmap_populate

All current users of the altmap are in the memory hotplug code and
they use __vmemmap_populate explicitly (via __sparse_mem_map_populate).
Complain if somebody uses vmemmap_populate with altmap registered
because that could be an unexpected usage. Also call __vmemmap_populate
with NULL from that code path.
