We wanted to include in the "details" file, which is otherwise a direct copy of
the SCAN_STATUS MSR. Making sure the software error codes didn't overlap
with any h/w generated codes seemed like a good idea.

But maybe we should have done this with additional string values in the status
file:

Current:

pass
untested
fail

Add a couple of new options for the s/w cases:

sw_timeout
sw_retries_exceeded
