[PATCH tip:x86/urgent] x86-32, NUMA: Fix ACPI NUMA init broken by recent x86-64 change

[Tejun Heo <tj@kernel.org>]

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 breking 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.
