Fix segmentation fault for NULL confname in SAVE_CONFIG

When wpa_supplicant interface is added without a configuration file, the
SAVE_CONFIG command causes a segmentation fault due to referencing a
NULL pointer if the update_config parameter is first explicitly enabled.

Fix the issue by checking the confname for NULL before saving
configuration.
