net: skip taking rtnl_lock for queue GET

Skip taking rtnl_lock for queue GET ops on devices which opt
into running all ops under the instance lock.

Jakub Kicinski (11):
  net: bubble up taking netdev instance lock to callers of
    net_devmem_unbind_dmabuf()
  net: remove netif_set_real_num_rx_queues() helper for when SYSFS=n
  net: constify dev pointer in misc instance lock helpers
  net: explain "protection types" for the instance lock
  net: designate queue counts as "double ops protected" by instance lock
  net: designate queue -> napi linking as "ops protected"
  net: protect rxq->mp_params with the instance lock
  net: make NETDEV_UNREGISTER and instance lock more consistent
  net: designate XSK pool pointers in queues as "ops protected"
  netdev: add "ops compat locking" helpers
  netdev: don't hold rtnl_lock over nl queue info get when possible
