net, xdp, xsk: fix __sk_mark_napi_id_once napi_id error
Stephen reported the following build error for !CONFIG_NET_RX_BUSY_POLL
built kernels:
In file included from fs/select.c:32:
include/net/busy_poll.h: In function 'sk_mark_napi_id_once':
include/net/busy_poll.h:150:36: error: 'const struct sk_buff' has no member named 'napi_id'
150 | __sk_mark_napi_id_once_xdp(sk, skb->napi_id);
| ^~
Fix it by wrapping a CONFIG_NET_RX_BUSY_POLL around the helpers.
Fixes: b02e5a0ebb17 ("xsk: Propagate napi_id to XDP socket Rx path")
