[PATCH AUTOSEL 6.14 02/44] drm/virtio: Set missing bo->attached flag

[Sasha Levin]

From: Dmitry Osipenko <dmitry.osipenko@xxxxxxxxxxxxx>

[ Upstream commit ffda6454267d0b870f3a09945a7ce88137b914a6 ]

VirtIO-GPU driver now supports detachment of shmem BOs from host, but
doing it only for imported dma-bufs. Mark all shmem BOs as attached, not
just dma-bufs. This is a minor correction since detachment of a non-dmabuf
BOs not supported today.
