ipmi:ssif: Fix a memory leak when scanning for an adapter
The adapter scan ssif_info_find() sets info->adapter_name if the adapter info came from SMBIOS, as it's not set in that case. However, this function can be called more than once, and it will leak the adapter name if it had already been set. So check for NULL before setting it.
