When CONFIG_SYSFS is not set, the kernel fails to compile:

     net/core/page_pool_user.c:368:45: error: implicit declaration of function 'get_netdev_rx_queue_index' [-Werror=implicit-function-declaration]
      368 |                 if (pool->slow.queue_idx == get_netdev_rx_queue_index(rxq)) {
          |                                             ^~~~~~~~~~~~~~~~~~~~~~~~~

When CONFIG_SYSFS is not set, get_netdev_rx_queue_index() is not defined
as well.

Fix by removing the ifdef around get_netdev_rx_queue_index(). It is not
needed anymore after commit e817f856 ("xdp: generic XDP handling of
xdp_rxq_info") removed most of the CONFIG_SYSFS ifdefs.

Fixes: 0f921404
