x86-64, NUMA: Unify {acpi|amd}_{numa_init|scan_nodes}() arguments and return values

Browse source 
The functions used during NUMA initialization - *_numa_init() and
*_scan_nodes() - have different arguments and return values.  Unify
them such that they all take no argument and return 0 on success and
-errno on failure.  This is in preparation for further NUMA init
cleanups.
