[libvirt] [PATCH 2/5] conf: Return error when resolution values are invalid
Report an error and return NULL when either the 'x' or 'y' resolution
values cannot be converted to unsigned integers rather than returning
the incomplete 'def' variable. Switch 'def' to an autofree variable to
simplify the logic and remove the goto.
