A change similar to #18491.
GRPC_CLOSURE_RUN runs the closure immediately. In our case, if we do that, we can end up with a use-after-free kind of bug, since we need to reference some elements in the op structure even after scheduling the closure.
By scheduling instead of running, we guarantee that the closures will not be run before we are done using the struct since we are using a combiner.
