Fix inverted return value from dbus_connection_read_write()

    * dbus/dbus-connection.c (_dbus_connection_read_write_dispatch):
      The double negation re no_progress_possible was obviously too
      confusing: the path for dispatch = FALSE would return an inverted
      status. So make it progress_possible and fix the logic.
