net: macsec: fix rtnl locking issue
netdev_update_features() must be called with the rtnl lock taken. Not
doing so triggers a warning, as ASSERT_RTNL() is used in
__netdev_update_features(), the first function called by
netdev_update_features(). Fix this.
Fixes: c850240b6c41 ("net: macsec: report real_dev features when HW offloading is enabled")
