xdp: XDP_REDIRECT should check IFF_UP and MTU
Otherwise we end up with attempting to send packets from down devices
or to send oversized packets, which may cause unexpected driver/device
behaviour. Generic XDP has already done this check, so reuse the logic
in native XDP.
Fixes: 814abfabef3c ("xdp: add bpf_redirect helper function")
