Fixed an error when reading a DEF file using generated vias in a 

non-default rule.  The code was first failing to identify the via
cut type from the generated via record, and then it was failing
to return to the non-default rule width after the route exits the
via.  Both issues have been fixed.  Thanks to Sylvain Munaut for
providing a reproducible test case.
