check_vintf: Clear error message when we are ignoring it.

In the case of NAME_NOT_FOUND, we generally pretend that no error
happen, so in addition of pretending that listFiles() returned OK, we
also need to clear the error message, or it would be leaked into verdict
message about why files are incompatible, which can be confusing for
developers.
