In virtio test, on guest
1. Bind virtio port to igb_uio driver;
2. Remove igb_uio module;
3. Bind virtio port to virtio-pci driver, it fails and reports:
"Error - no supported modules are loaded"
The tool should check the to-be-bound driver flag, if it is dpdk
driver(igb_uio, vfio etc),
and the corresponding module is not loaded, then exit, otherwise, just report a
warning,
and continue to bind the non-dpdk driver(like virtio-pci) to dev.
