geneve: allow changing DF behavior after creation

Currently, trying to change the DF parameter of a geneve device does
nothing:

    # ip -d link show geneve1
    14: geneve1: <snip>
        link/ether <snip>
        geneve id 1 remote 10.0.0.1 ttl auto df set dstport 6081 <snip>
    # ip link set geneve1 type geneve id 1 df unset
    # ip -d link show geneve1
    14: geneve1: <snip>
        link/ether <snip>
        geneve id 1 remote 10.0.0.1 ttl auto df set dstport 6081 <snip>

We just need to update the value in geneve_changelink.
