Ryan Neph 5489930113 drm/virtio: exbuf->fence_fd unmodified on interrupted wait
[ Upstream commit 8f20660f053cefd4693e69cfff9cf58f4f7c4929 ]

An interrupted dma_fence_wait() becomes an -ERESTARTSYS returned
to userspace ioctl(DRM_IOCTL_VIRTGPU_EXECBUFFER) calls, prompting to
retry the ioctl(), but the passed exbuf->fence_fd has been reset to -1,
making the retry attempt fail at sync_file_get_fence().

The uapi for DRM_IOCTL_VIRTGPU_EXECBUFFER is changed to retain the
passed value for exbuf->fence_fd when returning anything besides a
successful result from the ioctl.

Fixes: 2cd7b6f08b ("drm/virtio: add in/out fence support for explicit synchronization")
