bareudp: Use rtnl_dereference() in bareudp_sock_release().

kernel test robot reported sparse warning in bareudp_sock_release():

  drivers/net/bareudp.c:288:12: warning: incorrect type in assignment (different address spaces)
  drivers/net/bareudp.c:288:12:    expected struct sock *sk
  drivers/net/bareudp.c:288:12:    got struct sock [noderef] __rcu *sk

The warning is not new and exists since the initial bareudp commit
571912c69f0e ("net: UDP tunnel encapsulation module for tunnelling
different protocols like MPLS, IP, NSH etc.").

Let's use rtnl_dereference().

Note that bareudp_sock_release() is called from bareudp_stop()
under RTNL, so there is no real issue even without the helper.
