Handle invalid struct members 

When something goes wrong when parsing a struct member, e.g. the type does
not exist, a nullptr is added to the struct member list. This will cause a
crash when iterating over the list.

E.g.

```
struct packed {
  logc x;
} s;
```

Add a check so that nullptr members are not added to the list.
