sparc64: ldc_connect() should not return EINVAL when handshake is in progress.
The LDC handshake could have been asynchronously triggered after ldc_bind() enables the ldc_rx() receive interrupt-handler (and thus intercepts incoming control packets) and before vio_port_up() calls ldc_connect(). If that is the case, ldc_connect() should return 0 and let the state-machine progress.
