sink-input: change bool save_sink to char *preferred_sink

Browse source 
The finial objective is to store the preferred sink name in the
sink-input struct, and use module-stream-restore to save and restore
it.

This patch just replaces the save_sink with preferred_sink, and tries
to keep the original logic.
