net/mlx5e: Fix VXLAN configuration restore after function reload

Browse Source 
[ Upstream commit b3c2ed21c0 ]

When detaching netdev, remove vxlan port configuration using
udp_tunnel_drop_rx_info. During function reload, configuration will be
restored using udp_tunnel_get_rx_info. This ensures sync between
firmware and driver. Use udp_tunnel_get_rx_info even if its physical
interface is down.
