esound,streams: Fix some crashes.
After the rework to the add pa_sink_input_new_data_set_sink() (and the source equiv) calling with a NULL sink object will hit an assert. This caused crashes with the esd protocol and there was the potential (albeit unlikely) for a crash when creating a sink input without any sinks available (module-always-sink mitigates this risk but it's still a potential crasher).
