[Qemu-ppc] [PATCH 28/33] tests/qgraph: virtio-blk test node

[Emanuele Giuseppe Esposito]

Convert tests/virtio-blk-test in qgraph test node,
virtio-blk-test. This test consumes a virtio-blk interface
and checks that its function return the expected values.

Some functions are implemented only for virtio-blk-pci, so they
don't consume virtio-blk, but virtio-blk-pci

Note that this test does not allocate any virtio-blk structure,
it's all done by the qtest walking graph mechanism
