        Fix broken workspace switching from my previous commit.

        * src/display.c: (meta_display_begin_grab_op): don't
        leak a pointer grab if we fail to grab the keyboard.

        * src/keybindings.c: (meta_screen_grab_keys): check
        screen->all_keys_grabbed.
        (meta_screen_grab_all_keys): regrab our standard
        bindings if we fail.
        (handle_workspace_switch): revert to our previous
        behaviour of using the last focused window to do
        the grab upon. Only use the RootWindow if there
        isn't anything else to use.

        * src/screen.c: (meta_screen_new): initialise
        all_keys_grabbed.
