Peter Krempa c1576ad519 Add support for 'dpofua' setting for SCSI disks
Add the 'dpofua' setting in the XML and for the qemu driver.

DPO - Disable Page Out and FUA - Force Unit Access are two features
implemented by SCSI disks (either both together or neither of them)
which influence how caching is handled. QEMU provides a good default
but in certain specific occasions changing the default may have
performance benefits.

Add support for setting them via the XML.
