[PATCH] drm/amdgpu: fix no-vmid job

[Chunming Zhou]

[  132.036658] amdgpu 0000:22:00.0: VM IB without ID
[  132.036709] [drm:amdgpu_job_run [amdgpu]] *ERROR* Error scheduling IBs (-22)
[  132.036755] [drm:amd_sched_main [amdgpu]] *ERROR* Failed to run job!

root cause is fence is signaled during sync transfer.
