Possible memory leak in pygi-invoke.c

[Damien Caliste <damien caliste cea fr>]

Hello,

   Using PyGI in my code, I notice that each function call costs memory
that is not released after. In my opinion,
the function _wrap_g_function_info_invoke() does not free memory
allocated in the structure "state" in case of working status, while
_free_invocation_state() is indeed call in case of error. I suggest to
call the _free routine before the return line, as done in the attached
patch.

   What do you think ?

Damien.
