cdrom_id: Fix state for fresh DVD-RW
Fresh DVD-RW in restricted overwite mode reports itself as "appendable"; change
it to "blank" to make it consistent with what gets reported after blanking, and
what userspace expects.
For the exotic case where some uses multi-track recording on a DVD-RW in
sequential mode, we need to tell apart sequential and restricted overwrite
modes, so keep separate states for them internally.
