virtgpu_crossdomain: Handle buffer special case

Browse source 
Blob formats (aka buffers) get represented as R8 textures with height
of one and width==size.  These actually have no particular stride
requirement, even though the host might ask for a pitch that would make
sense for a 2D R8 texture with height greater than one.
