Use __virtio16_to_cpu() to read `max_virtqueue_pairs` field in virtio_net_config since its type is __virtio16.
This silences the following warning when building with `make C=2`:
../drivers/vdpa/vdpa.c:811:19: warning: cast to restricted __le16 ../drivers/vdpa/vdpa.c:811:19: warning: cast from restricted __virtio16
