net: ethernet: ti: cpsw: fix ASSERT_RTNL() warning during resume



netif_set_real_num_tx/rx_queues() are required to be called with rtnl_lock
taken, otherwise ASSERT_RTNL() warning will be triggered - which happens
now during System resume from suspend:
cpsw_resume()
|- cpsw_ndo_open()
  |- netif_set_real_num_tx/rx_queues()
     |- ASSERT_RTNL();

Hence, fix it by surrounding cpsw_ndo_open() by rtnl_lock/unlock() calls.
