tag: id3v2: A track/volume number or count of 0 does not make sense, just ignore...

Original commit message from CVS:
* gst-libs/gst/tag/id3v2frames.c: (id3v2_tag_to_taglist):
A track/volume number or count of 0 does not make sense,
just ignore it along with negative numbers (a tag might
only contain a track count without a track number).
