Note that prior to 2e670cd, there was no crash but only the last
"srv6-sid-structure" was displayed. A "srv6-sid-structure" should be
displayed for each "sid". This commit also fix this.

Was:

> "srv6-lan-endx-sid": [
>   {
>     "sid": "fc00:0:1:1::",
>     "weight": 0,
>     "algorithm": "SPF",
>     "neighbor-id": "0000.0000.0002"
>   },
>   {
>     "sid": "fc00:0:1:2::",
>     "weight": 0,
>     "algorithm": "SPF",
>     "neighbor-id": "0000.0000.0003"
>   }
> ],
> "srv6-sid-structure": {
>   "loc-block-len": 32,
>   "loc-node-len": 16,
>   "func-len": 16,
>   "arg-len": 0
> },

Now (srv6-sid-structure are identical but they are not always):

> "srv6-lan-endx-sid": [
>   {
>     "sid": "fc00:0:1:1::",
>     "algorithm": "SPF",
>     "neighbor-id": "0000.0000.0002",
>     "srv6-sid-structure": {

>       "loc-node-len": 16,
>       "func-len": 8,
>       "arg-len": 0
>     },
>   },
>   {
