Non-lenient JsonWriter.value for NaN or Infinity writes name before throwing exception

For a non-lenient JsonWriter the methods `value(double)` and `value(Number)` write the name of the current JSON property before checking if the value is valid and throwing an exception.

This is problematic for JsonWriters which are supposed to not serialize properties with `null` values (`setSerializeNulls(false)`):
```java
public void testSerializeNulls() throws IOException {
StringWriter stringWriter = new StringWriter();
JsonWriter jsonWriter = new JsonWriter(stringWriter);
jsonWriter.setSerializeNulls(false);
jsonWriter.beginObject();

// Make sure that methods throwing exceptions do not write
// name
jsonWriter.name("test");
try {
// value(double)
jsonWriter.value(Double.NaN);
} catch (IllegalArgumentException expected) {
}
jsonWriter.nullValue();

jsonWriter.endObject();
// Fails because `test:null` has been written
assertEquals("{}", stringWriter.toString());
}
```
