While creating a uobject every create reaches a point where the uobject is fully initialized. For ioctls that go on to copy_to_user this means they need to open code the destruction of a fully created uobject - ie the RDMA_REMOVE_DESTROY sort of flow. Open coding this creates bugs, eg the CQ does not properly flush the events list when it does its error unwind. Provide a uverbs_finalize_uobj_create() function which indicates that the uobject is fully initialized and that abort should call to destroy_hw to destroy the uobj->object and related. Methods can call this function if they go on to have error cases after setting uobj->object. Once done those error cases can simply do return, without an error unwind.
