scsi-bus: Add MAINTENANCE_IN and MAINTENANCE_OUT SCSIRequest xfer and mode assignments 

This patch updates hw/scsi-bus.c to add MAINTENANCE_IN and MAINTENANCE_OUT case in
scsi_req_length() for TYPE_ROM with MMC commands.  It also adds the MAINTENANCE_OUT
case in scsi_req_xfer_mode() to set SCSI_XFER_TO_DEV for outgoing write data.
