cdrom_id: Drop MEDIA_SESSION_NEXT for DVD-RW-RO

Commit cf2205a fixed the media status for fresh DVD-RW in restricted overwrite
mode, but missed a detail: We should not report the ID_CDROM_MEDIA_SESSION_NEXT
property either, since in that mode you can never append tracks/sessions; this
just works in sequential mode.
