Don't spam server logs if CLI server receives an access=7 INI setting with the current value

### HHVM Version

3.23.2

### Standalone code, or other way to reproduce the problem

Use CLI server, run anything

### Expected result

A whole load of log spam, eg

```
CLI server received an invalid INI setting: date.timezone (access = 7)
CLI server received an invalid INI setting: mbstring.substitute_character (access = 7)
CLI server received an invalid INI setting: memcache.hash_function (access = 7)
CLI server received an invalid INI setting: memcache.hash_strategy (access = 7)
```

### Actual result

No log spam for ini settings where CLI client config matches server config
