isisd: fix srv6 exit statements

Fix missing and misplaced `exit` statements to `show running-config` output.

Before:
```
router isis ISIS_CORE
 [...]
 segment-routing srv6
  locator ISIS_LOC
 exit    <<<<<<< always placed after locator
  node-msd
    [...]
  exit    <<<<<<< missng
  interface dum6
exit
```

After:
```
router isis ISIS_CORE
 [...]
 segment-routing srv6
  locator ISIS_LOC
  node-msd
   [...]
  exit
  interface dum6
 exit
exit
```
