Subject: [PATCH] virtio-gpu: fix compilation warnings

Update snprintf format in virtgpu_fence.c and virtgpu_debugfs.c to fix the
following compilation warnings:

C [M]  drivers/gpu/drm/virtio/virtgpu_fence.o
drivers/gpu/drm/virtio/virtgpu_fence.c: In function ‘virtio_timeline_value_str’ :
drivers/gpu/drm/virtio/virtgpu_fence.c:64:2: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘long long int’ [-Wformat=]
  snprintf(str, size, "%lu", atomic64_read(&fence->drv->last_seq));
  ^
  CC [M]  drivers/gpu/drm/virtio/virtgpu_debugfs.o
drivers/gpu/drm/virtio/virtgpu_debugfs.c: In function ‘virtio_gpu_debugfs_irq_info’:
drivers/gpu/drm/virtio/virtgpu_debugfs.c:39:6: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 3 has type ‘long long int’ [-Wformat=]
      vgdev->fence_drv.sync_seq);
      ^
