octeontx2-pf: Reconfigure RSS table after enabling AF_XDP zerocopy on rx queue

RSS table needs to be reconfigured once a rx queue is enabled or
disabled for AF_XDP zerocopy support. After enabling UMEM on a rx queue,
that queue should not be part of RSS queue selection algorithm.
Similarly the queue should be considered again after UMEM is disabled.
