Setting render target usage on a P8 surface for example would fail surface
creation, while such surfaces can't be used for actual rendering anyway. Tests
confirm that surface creation is supposed to succeed for P8 surfaces with both
DDSCAPS_SYSTEMMEMORY and DDSCAPS_3DDEVICE set.

Similar to AddAttachedSurface() / DeleteAttachedSurface(), we should Release
the interface version that we stored. (And actually store the interface that
we AddRef.)
