isisd: Show correct level information for `show isis interface detail json`

Having this configuration:

```
!
interface r1-eth0
 ip address 10.0.0.1/30
 ip router isis 1
 isis priority 44 level-1
 isis priority 88 level-2
 isis csnp-interval 90 level-1
 isis csnp-interval 99 level-2
 isis psnp-interval 70 level-1
 isis psnp-interval 50 level-2
 isis hello-interval level-1 120
 isis hello-interval level-2 150

!
interface r1-eth1
 ip address 10.0.0.10/30
 ip router isis 1
!
interface lo
 ip address 192.0.2.1/32
 ip router isis 1
 isis passive
!
router isis 1
net 49.0000.0000.0000.0001.00
 metric-style wide
```

Produces:

```
