This is a small NET_LWIP cleanup. Instead of re-creating a struct netif from a struct udevice every time a nework operation is requested (dhcp, ping, etc.), store the netif inside the udevice.
No functional change is expected, but the behavior of the network stack might change a bit since not removing the device may have impacts on various states in the stack (the ARP cache for instance).
