[lvc-project] [PATCH 5.10/5.15] drm/vmwgfx: drop dma_buf reference on foreign-fd prime import

[Sasha Levin]

> ttm_prime_fd_to_handle() returns -ENOSYS when the imported fd's
> dma_buf->ops do not match the ttm_object_device's ops, but does so
> without releasing the reference acquired by dma_buf_get().

Queued for 5.15 and 5.10, thanks.
