Switch over all parts of EAL to use heap ID instead of NUMA node
ID to identify heaps. Heap ID for DPDK-internal heaps is NUMA
node's index within the detected NUMA node list. Heap ID for
external heaps will be order of their creation.

malloc_socket_to_heap_id can return -1 so it requires to handle that
possibility.
Not really, this is called from memseg walk function - we know the msl
and its socket ID are valid. Or at least something has gone *very* wrong
if we got a -1 result :) However, i guess this check won't hurt.
