sqlite3: fix build when threads are not used/available

When threads are not used/available, a function in the sqlite3 extension
ends up with a label at the end:

    void _pysqlite_final_callback(sqlite3_context* context)
    {
        PyObject* function_result;
        PyObject** aggregate_instance;
        int ok;

    #ifdef WITH_THREAD
        PyGILState_STATE threadstate;

        threadstate = PyGILState_Ensure();
    #endif

        aggregate_instance = (PyObject**)sqlite3_aggregate_context(context, sizeof(PyObject*));
        if (!*aggregate_instance) {
            goto error;
        }

        [......]

    error:
    #ifdef WITH_THREAD
        PyGILState_Release(threadstate);
    #endif
    }

This is not valid, and gcc complains.

Fix that by adding a dummy statement after the label, so that the label
is never the last statement of the function.
