Don't call Fset_window_buffer from C code.

* frame.c (make_frame_without_minibuffer, make_minibuffer_frame)
(delete_frame, Fmake_frame_invisible, Ficonify_frame):
* minibuf.c (choose_minibuf_frame, read_minibuf):
* w32fns.c (x_create_tip_frame):
* xfns.c (x_create_tip_frame): Call set_window_buffer instead of
Fset_window_buffer (Bug#11984, Bug#12025, Bug#12026).
