6723228: NUMA allocator: assert(lgrp_id != -1, "No lgrp_id set")

6723229: NUMA allocator: assert(lgrp_num > 0, "There should be at least one locality group")

The fix takes care of the assertion triggered during TLAB resizing after reconfiguration. Also it now handles a defect in the topology graph, in which a single leaf node doesn't have memory.
