This is freed both here and in the caller (virtio_gpu_vram_map()) so
it's a double free. The correct place is only in the caller.

object")

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the

Pinned pages are not properly accounted particularly when
mapping error occurs on IOTLB update. Clean up dangling
pinned pages for the error path.
The memory usage for bookkeeping pinned pages is reverted
to what it was before: only one single free page is needed.
This helps reduce the host memory
This reverts commit 7ed9e3d97c32d969caded2dfb6e67c1a2cc5a0b1.
