sd-device: never return NULL+0
It is highly confusing if a getter function returns 0, but the value is set to NULL. This, right now, triggers assertions as code relies on the returned values to be non-NULL. Like with sd-bus-creds and friends, return 0 only if a value is actually available. Discussed with Tom, and actually fixes real bugs as in #512.
