refcount: typecast function for calling on free

All of the functions called to free the refcounted structure are doing a
typecast from (void*) to their own type taht is being free'd. This
really is not needed and the refcount interface is made a little simpler
without the requirement of typecasting.

With this small improvement in the API, all callers are updated too.
