[resend 1/5] ddraw: check if surface is a mipmap sublevel through caps in ddraw_surface7_GetPriority

[Riccardo Bortolato]

Hey Stefan,

I'm going to let every ddraw_surface have its own wined3d_texture (in
the refcount patch), but I cannot leave that check ( ||
!surface->wined3d_texture) in place when doing the change since it
will always be false (and thus, useless).
It seems to me there's no good way to do this.

Ciao,
Riccardo
