Daniel Borkmann ba0581749f 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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
