[SCSI] Support devices with protection information

Implement support for DMA of protection information for devices that
are data integrity capable.

- Add support for mapping an extra scatter-gather list containing
   the protection information.

- Allocate protection scsi_data_buffer if host is DIX (integrity DMA)
   capable.

- Accessor function for checking whether a device has protection
   enabled.
