cdrom_id: Don't read beyond "last track" in TOC

Read the first and last track from the TOC header, and do not go beyond that
stated number of tracks when reading the TOC. Otherwise we interpret random
data which leads to bogus tracks. (Reported on an IronKey, which reported 1
data track, and 4 audio tracks which weren't actually present.)
