[BUGFIX] cfg80211: don't require RTNL held for regdomain reads
The whole code is set up to allow RCU reads of this data, but
then uses rtnl_dereference() which requires the RTNL. Convert
it to rcu_dereference_rtnl() which makes it require only RCU
or the RTNL, to allow RCU-protected reading of the data.
