Subject: [PATCH net-next v2] memory-provider: fix compilation issue without SYSFS
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 e817f85652c1 ("xdp: generic XDP handling of
xdp_rxq_info") removed most of the CONFIG_SYSFS ifdefs.
Fixes: 0f9214046893 ("memory-provider: dmabuf devmem memory provider")

v2:
- I (mina) sent v2 of Matthieu's fix.
- Remove the ifdef around the function definition. It's not needed
anymore (Jakub)
