qat_plugin: use vfio-pci as the default driver

Browse Source 
vfio-pci uses IOMMU memory protection and is a safer default.

@ -59,6 +59,8 @@ By default, the device plugin supports these QuickAssist devices: DH895xCC, C62
Use the `kernel-vf-drivers flag` to specify the vf Device Driver for the particular QAT device. For more information, refer to [Intel QAT Crypto Poll Mode Driver](https://dpdk.org/doc/guides/cryptodevs/qat.html).
`-dpdk-driver` is set to `vfio-pci` by default since it is more robust and secure driver compared with `igb_uio`. See [DPDK Linux Driver Guide](http://dpdk.org/doc/guides/linux_gsg/linux_drivers.html) for more information.
### Build QAT device plugin Docker image:
```
$ cd $GOPATH/src/github.com/intel/intel-device-plugins-for-kubernetes
