USB: serial: io_ti: fix I/O after disconnect commit 2330d0a853da260d8a9834a70df448032b9ff623 upstream. Cancel the heartbeat work on driver unbind in order to avoid I/O after disconnect in case the port is held open. Note that the cancel in release() is still needed to stop the heartbeat after late probe errors.
