Hello:

After free xsk_pool, there is possibility that napi polling is still running in the middle, thus causes a kernel crash due to kernel NULL pointer dereference of rx_q->xsk_pool and tx_q->xsk_pool.

Fix this by changing the XDP pool setup sequence to:

1. disable napi before free xsk_pool
2. enable napi after init xsk_pool
