Thomas Hellstrom a741acc012 drm/vmwgfx: Make sure user-space can't DMA across buffer object boundaries v2 ...

commit cbd75e97a5 upstream.

We already check that the buffer object we're accessing is registered with
the file. Now also make sure that we can't DMA across buffer object boundaries.

v2: Code commenting update.
