scsi-disk: add stubs for more MMC commands
This patch adds a few stub implementations for MMC commands to scsi-disk, to be filled in later in the series. It also adds to scsi-defs.h constants for commands implemented by ide/atapi.c, when missing. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
