Corey Berla 111929593a mountoperation: Free user_widgets list upon dialog destruction 
There's a list user_widgets that contains all of the entries and
selections during authentication.  This is only freed  upon
finalizing the GtkMountOperation.  It's possible (and true for the
GVFS SMB implementation) that a MountOperation can have the
gtk_mount_operation_ask_password_do_gtk () function called multiple
times (i.e. bad password).  The user_widgets list grows with now
invalid pointers to old widgets (causing unexpected behavior and
seg faults).

Free the user_widgets list upon dialog destruction, we don't need it
anymore.

* GtkMountOperation:
*
* `GtkMountOperation` is an implementation of `GMountOperation`.
*
* The functions and objects described here make working with GTK and
* GIO more convenient.
*
* `GtkMountOperation` is needed when mounting volumes:
* It is an implementation of `GMountOperation` that can be used with
* GIO functions for mounting volumes such as
* g_file_mount_enclosing_volume(), g_file_mount_mountable(),
* g_volume_mount(), g_mount_unmount_with_operation() and others.
*
* When necessary, `GtkMountOperation` shows dialogs to let the user
* enter passwords, ask questions or show processes blocking unmount.
