All the virtio pci device is set to class code 0x010000, this is wrong.
This patch sets the correct class code and makes lspci report correct
class type. For example, the net device:
Before:
$ lspci
00:03.0 SCSI storage controller: Red Hat, Inc Virtio network device
After:
$ lspci
00:03.0 Ethernet controller: Red Hat, Inc Virtio network device
