6779436: NUMA allocator: libnuma expects certain size of the buffer in numa_node_to_cpus()

Browse source 
In os::Linux::rebuild_cpu_to_node_map() fix the size of the CPU bitmap. Fixed arithmetic in MutableNUMASpace::adaptive_chunk_size() that could cause overflows and underflows of the chunk_size variable.
