r600g: don't allocate separate depth and stencil for transfer textures on EG

Browse Source 
The state tracker expects depth and stencil pixels interleaved.
Evergreen can bind an interleaved depth-stencil resource as a colorbuffer,
but not as a zbuffer.

The hardware can do the interleaving for us when decompressing.
