st/nine: Fix remaining swapchain tests

Return D3DERR_INVALIDCALL instead of E_POINTER.
On error set ppBackBuffer to NULL.

Multiple swapchains can only be created in windowed mode as
windowed swapchain.

Set backbuffer to NULL in NineDevice9_GetBackBuffer, but not
in NineSwapChain9_GetBackBuffer.

This fixes all WINE's device.c test_swapchain() tests.
