vo_gpu: d3d11_helpers: don't try BGRA_SUPPORT

Browse Source 
The D3D11_CREATE_DEVICE_BGRA_SUPPORT flag doesn't enable support for
BGRA textures. BGRA textures will be supported whether or not the flag
is passed. The flag just fails device creation if they are not supported
as an API convenience for programs that need BGRA textures, such as
programs that use D2D or D3D9 interop. We can handle devices without
BGRA support fine, so don't bother with the flag.
