Don't try to add the log_mf_h handler in sasl unless configured to do so.
The functions add_error_logger_mf/1 and delete_error_logger_mf/1 in sasl.erl are designed to do nothing if the handler configuration as returned by get_error_logger_mf/0 is 'undefined'. However, that function returns a triple {undefined,undefined,undefined} when the error_logger_mf_* configurations have not been set. This makes SASL always try to add the log_mf_h handler on startup, passing 'undefined' for each of the Dir, MaxB and MaxF parameters. The gen_event callback function log_mf_h:init/1 will then crash with a function_clause error, causing the handler to be silently removed again. This patch fixes the problem by making get_error_logger_mf/0 return the single atom 'undefined' as it is expected to do.
