The first for_each only do acpi_nfit_init_ars() for NFIT_SPA_VOLATILE

Can the result of nfit_spa_type(nfit_spa->spa) change as a result of
the first switch statement? That would be a reason why they are separate.
nfit_spa_type() just gets the type of *spa by querying a type-uuid
table. Also, according to the code shown below, we can find that it
doesn't change anything.
int nfit_spa_type(struct acpi_nfit_system_address *spa)
{
guid_t guid;
int i;
import_guid(&guid, spa->range_guid);
for (i = 0; i < NFIT_UUID_MAX; i++)
if (guid_equal(to_nfit_uuid(i), &guid))
return i;
return -1;
}

Thanks,
Ruan.
