[Revert] id3 title display playlist_viewer.c

Browse source 
reading the disk works fine for on disk playlist but
trying to read from the disk with the current playlist
becomes unbearably slow

removes the static playlist_track_info prefering the unused one
already on the stack from search_playlist()
