drm/vmwgfx: Return error code from vmw_execbuf_copy_fence_user
commit 728354c005c36eaf44b6e5552372b67e60d17f56 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.
