  1. bpf: lb: clean up saddr handling in __lb*_rev_nat() 

    As workaround for older kernels, we currently copy the new_saddr from the
NAT entry to a temporary stack variable.

But with the bump to kernel 4.19 this is no longer needed, we can just
access the NAT entry directly.

  3. bpf: lb: remove redundant reset of key->backend_slot 

    For better or worse, lb*_lookup_service() already does this for us.
