Ido Schimmel 3ebaf6da07 net: sched: Do not assume RTNL is held in tunnel key action helpers 
The cited commit removed RTNL from tc_setup_flow_action(), but the
function calls two tunnel key action helpers that use rtnl_dereference()
to fetch the action's parameters. This leads to "suspicious RCU usage"
warnings [1][2].

Change the helpers to use rcu_dereference_protected() while requiring
the action's lock to be held. This is safe because the two helpers are
only called from tc_setup_flow_action() which acquires the lock.
