x86-64, NUMA: Restructure initmem_init()
Reorganize initmem_init() such that, * Different NUMA init methods are iterated in a consistent way. * Each iteration re-initializes all the parameters and different method can be tried after a failure. * Dummy init is handled the same as other methods. Apart from how retry after failure, this patch doesn't change the behavior. The call sequences are kept equivalent across the conversion. After the change, bad_srat() doesn't need to clear apic to node mapping or worry about numa_off. Simplified accordingly.
