Subject: [PATCH] sd-bus: do not return negative errno when unknown name is
 specified

When 'recursive' is false, then sd_bus_track_remove_name() does not
return negative errno when unknown name is specified. Let's follow the
same pattern for the case that 'recursive' is true.

(cherry picked from commit 55bfacc6c33eaf3475762e71172b2ef504be5af8)
