Reconfigure the NIC will fail because lack of the
initialization logic of queue configuration pointer.
Fix this by adding the correct initialization logic.

From: Xinying Yu <xinying.yu@corigine.com>

The ctrl words of vDPA is locate on the extend word, so should
use the 'nfp_ext_reconfig()' rather than 'nfp_reconfig()'.

Also replace the misuse of 'NFP_NET_CFG_CTRL_SCATTER' macro
with 'NFP_NET_CFG_CTRL_VIRTIO'.

From: Xinying Yu <xinying.yu@corigine.com>

The ctrl words of vDPA is located on the extended word, so it
should use the 'nfp_ext_reconfig()' rather than 'nfp_reconfig()'.

Also replace the misuse of 'NFP_NET_CFG_CTRL_SCATTER' macro
with 'NFP_NET_CFG_CTRL_VIRTIO'.

Reconfigure the NIC will fail because lack of the
initialization logic of queue configuration pointer.
Fix this by adding the correct initialization logic.
