x86-32, NUMA: Fix ACPI NUMA init broken by recent x86-64 change

Commit d8fc3afc49 (x86, NUMA: Move *_numa_init() invocations
into initmem_init()) moved acpi_numa_init() call into NUMA
initmem_init() but forgot to update 32bit NUMA init breaking ACPI
NUMA configuration for 32bit.

acpi_numa_init() call was later moved again to srat_64.c. Match
it by adding the call to get_memcfg_from_srat() in srat_32.c.
