ext/vorbis/vorbisdec.c: Small cleanups.

Browse source 
Original commit message from CVS:
* ext/vorbis/vorbisdec.c: (vorbis_dec_push_forward),
(vorbis_handle_data_packet), (vorbis_dec_decode_buffer),
(vorbis_dec_flush_decode):
Small cleanups.
Don't try to add invalid timestamps.
Clipping will unref the buffer.
