ACPI: NUMA: Fix the logic of getting the fake_pxm value
The for loop does not iterate over the last element of the node_to_pxm_map
array. This could lead to a conflict between the final fake_pxm value and
the existing pxm values. That is, the final fake_pxm value can not be
guaranteed to be an unused pxm value.
While at it, fix up white space in slit_valid().
