ice: improve updating ice_{t,r}x_ring::xsk_pool

xsk_buff_pool pointers that ice ring structs hold are updated via ndo_bpf that is executed in process context while it can be read by remote CPU at the same time within NAPI poll. Use synchronize_net() after pointer update and {READ,WRITE}_ONCE() when working with mentioned pointer.
