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