object_property_set_description() and object_class_property_set_description() fail only when property @name is not found. There are 85 calls of object_property_set_description() and object_class_property_set_description(). None of them can fail: * 84 immediately follow the creation of the property. * The one in spapr_rng_instance_init() refers to a property created in spapr_rng_class_init(), from spapr_rng_properties[]. Every one of them still gets to decide what to pass for @errp. 51 calls pass &error_abort, 32 calls pass NULL, one receives the error and propagates it to &error_abort, and one propagates it to &error_fatal. I'm actually surprised none of them violates the Error API. What are we gaining by letting callers handle the "property not found" error? Use when the property is not known to exist is simpler: you don't have to guard the call with a check. We haven't found such a use in 5+ years. Until we do, let's make life a bit simpler and drop the @errp parameter.
