x86/platform/uv: Fix printed information in calc_mmioh_map

Fix incorrect mask names and values in calc_mmioh_map() that caused it
to print wrong NASID information. And an unused blade position is not
an error condition, but will yield an invalid NASID value, so change
the invalid NASID message from an error to a debug message.
