[glibmm] giomm: AsyncInitiable: Correct errors.

[José Alburquerque <jaalburqu src gnome org>]

commit fa7ddca42b0a63cd57efdf336bae8e6a04e4c3f4
Author: José Alburquerque <jaalburqu svn gnome org>
Date:   Tue Aug 31 01:27:12 2010 -0400

    	giomm: AsyncInitiable: Correct errors.
    
    	* gio/src/asyncinitable.ccg (init_async_vfunc_callback): Take an extra
    	reference of the cancellable when calling the member virtual method so
    	the cancellable is not destroyed.
    	(init_async_vfunc): Don't create a copy of the SlotAsyncReady because
    	it would have already been copied in init_async() method invocation.
