====================
net: depend on instance lock for queue related netlink ops

netdev-genl used to be protected by rtnl_lock. In previous release
we already switched the queue management ops (for Rx zero-copy) to
the instance lock. This series converts other ops to depend on the
instance lock when possible.

Unfortunately queue related state is hard to lock (unlike NAPI)
as the process of switching the number of queues usually involves
a large reconfiguration of the driver. The reconfig process has
historically been under rtnl_lock, but for drivers which opt into
ops locking it is also under the instance lock. Leverage that
and conditionally take rtnl_lock or instance lock depending
on the device capabilities.
