Thomas Hellstrom 7fa5536f92 drm/vmwgfx: Return error code from vmw_execbuf_copy_fence_user ...

commit 728354c005 upstream.

The function was unconditionally returning 0, and a caller would have to
rely on the returned fence pointer being NULL to detect errors. However,
the function vmw_execbuf_copy_fence_user() would expect a non-zero error
code in that case and would BUG otherwise.

So make sure we return a proper non-zero error code if the fence pointer
returned is NULL.
