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.
