net: remove netif_set_real_num_rx_queues() helper for when SYSFS=n

Browse Source 
Since commit a953be53ce ("net-sysfs: add support for device-specific
rx queue sysfs attributes"), so for at least a decade now it is safe
to call net_rx_queue_update_kobjects() when SYSFS=n. That function
does its own ifdef-inery and will return 0. Remove the unnecessary
stub for netif_set_real_num_rx_queues().
