[PATCH 0/1] MR2235: dlls/dxgi: Don't warn on DXGI_ALPHA_MODE_UNSPECIFIED with wined3d

[David Gow (＠sulix)]

Wine's dxgi implementation doesn't handle the different DXGI_ALPHA_MODE
values, save for DXGI_ALPHA_MODE_IGNORE on both vkd3d (d3d12) and
wined3d (d3d11), but prints a fixme for DXGI_ALPHA_MODE_UNSPECIFIED for
wined3d but not vkd3d.

To match the behaviour between the two, and because the "Unspecified"
mode seems like it should always be acceptable to ignore, don't print a
fixme in the wined3d path either.

This eliminates the following warning:
010c:fixme:dxgi:wined3d_swapchain_desc_from_dxgi Ignoring alpha mode 0.
