Oleksandr Andrushchenko 5fa4e6f1c2 xen/gntdev: Fix dmabuf import with non-zero sgt offset 
It is possible that the scatter-gather table during dmabuf import has
non-zero offset of the data, but user-space doesn't expect that.
Fix this by failing the import, so user-space doesn't access wrong data.

Fixes: bf8dc55b1358 ("xen/gntdev: Implement dma-buf import functionality")
