Subject: mm: remove vmalloc_user_node_flags

Open code it in __bpf_map_area_alloc, which is the only caller.  Also
clean up __bpf_map_area_alloc to have a single vmalloc call with slightly
different flags instead of the current two different calls.

For this to compile for the nommu case add a __vmalloc_node_range stub to
nommu.c.
