[PATCH 1/2] drm/gpuvm: export drm_gpuvm_bo_destroy_not_in_lists()

[Daniel Pesic <danny.pesic@gmail.com>]

drm_gpuvm_bo_obtain_prealloc() currently calls this function directly to
destroy a losing preallocated drm_gpuvm_bo. Export it and promote its
comment to kernel-doc so the upcoming Rust GpuVmBoAlloc binding can call
it the same way.
