Don't shrink frame when using desktop-save-mode (Bug#19048).

* w32fns.c (x_set_tool_bar_lines): Always call
x_change_tool_bar_height (Bug#19048).
(x_change_tool_bar_height): Mark frame as garbaged since
adjust_frame_size might not have done that.
* xfns.c (x_set_tool_bar_lines): Always call
x_change_tool_bar_height (Bug#19048).
(x_change_tool_bar_height): Mark frame as garbaged since
adjust_frame_size might not have done that.
