Return early after initializing non-invokable methods

This fixes a bug introduced in
https://android-review.googlesource.com/c/platform/art/+/2216463
where we forgot to return after handling non-invokable methods.
We shouldn't fallback since it could initialize it with something other
than interpreter bridge.
