This is a natural use case, and instead of defining a wrapper to do this for us, let's just make this part of the API. Calling with NULL was not allowed, so this is not a breaking change to the interface. (After sd_event_source_is_enabled was originally added, we introduced sd_event_source_disable_unref() and other similar functions which accept NULL. So not accepting NULL here is likely to confuse people. Let's just make the API usable with minimal fuss.)
