.............................

In virtio_blk_device_init(), the memory which vdev point to is a static
member of "struct VirtIOBlkPCI", not heap memory, and it does not
get freed. So we shoule use virtio_common_cleanup() to clean this VirtIODevice
rather than virtio_cleanup(), which attempts to free the vdev.

This error was introduced by commit 05ff686536
recently.
