BigSwitch: Cfg.error call formatted incorrectly

[Kevin Benton]

In an exception handling case a config error is raised; however, the call is currently formatted incorrectly. It passes the details as a second parameter rather than performing the string formatting in place.

It also refers to strerror, which may not be present on all exception types that could be raised during the certificate retrieval.
