netdev-genl: Add an XSK attribute to queues
Expose a new per-queue nest attribute, xsk, which will be present for
queues that are being used for AF_XDP. If the queue is not being used for
AF_XDP, the nest will not be present.
In the future, this attribute can be extended to include more data about
XSK as it is needed.
