Change default PCI class of virtio-blk to PCI_CLASS_STORAGE_SCSI

Browse Source 
Windows virtio driver cannot pass DTM (certification) tests while the
storage class is PCI_CLASS_STORAGE_UNKNOWN.

A new qdev type is introduced to allow devices using the old class
to be created for compatibility with qemu-0.10.x.
