Avoid direct return from ecall(); fix #3441
...
There's incompatibility left for mruby.
When you return from `ensure` clause, mruby simply ignores the return
value. CRuby returns from the method squashing the exception raised.
```
def f
no_such_method() # NoMethodError
ensure
return 22
end
p f() # CRuby prints `22`
