[PATCH] drm/amdgpu: remove vm sanity check from amdgpu_vm_make_compute

[Xiaogang . Chen]

From: Xiaogang Chen <xiaogang.c...@amd.com>

Since we allow kfd and graphic operate on same GPU VM to have interoperation
between them GPU VM may have been used by graphic vm operations before kfd turn
a GFX VM into a compute VM. Remove vm clean checking at amdgpu_vm_make_compute.
