atapi/scsi-disk: make mode page values coherent between the two 

This patch adds to scsi-disk the missing mode page 0x01 for both disk
and CD-ROM drives, and mode page 0x0e for CD drives only.

A few offsets were wrong in atapi.c.  Also change the 2Ah mode page to
expose DVD media read capabilities in the IDE cdrom.  This lets you run
dvd+rw-mediainfo on the virtual DVD drives.
