ACPI/NUMA: Squash acpi_numa_memory_affinity_init() into acpi_parse_memory_affinity()

After removing architectural code the helper function
acpi_numa_memory_affinity_init() is no longer needed. Squash it into
acpi_parse_memory_affinity(). No functional changes intended.

While at it, fixing checkpatch complaints in code moved.
