mm/memblock: switch to use NUMA_NO_NODE instead of MAX_NUMNODES
It's recommended to use NUMA_NO_NODE everywhere to select "process any
node" behavior or to indicate that "no node id specified".
Hence, update __next_free_mem_range*() API's to accept both NUMA_NO_NODE
and MAX_NUMNODES, but emit warning once on MAX_NUMNODES, and correct
corresponding API's documentation to describe new behavior. Also,
update other memblock/nobootmem APIs where MAX_NUMNODES is used
dirrectly.
The change was suggested by Tejun Heo.
