net: ethtool: Fix suspicious rcu_dereference usage
The __ethtool_get_ts_info function can be called with or without the
rtnl lock held. When the rtnl lock is not held, using rtnl_dereference()
triggers a warning due to the lack of lock context.
Add an rcu_read_lock() to ensure the lock is acquired and to maintain
synchronization.
