shared/att: Call io_shutdown on ATT violations The existing code handles ATT protocol request timeouts and invalid incoming request PDUs by cleaning up the io structure via io_destroy. This doesn't always work, since this only terminates the connection if io_set_close_on_destroy has been set. Calling io_destroy to force a disconnect also has the added side-effect of not invoking the disconnect callback registered with struct io. This patch fixes these by calling io_shutdown on the io instead when required by ATT protocol specification. This both cleans up the connection regardless of whether or not close_on_unref has been set, and it triggers the disconnect callback via an EPOLLHUP event.
