[Libguestfs] [PATCH] java: fix memory leak in RStruct actions

[Pino Toscano]

The return value struct was freed using a simple free() instead of the
own cleanup function of each struct: this meant dynamically allocated
values (such as strings) were leaked.

Use the proper cleanup functions instead.
