drm/amdgpu: Forward VMID reservation errors

Otherwise userspace may be fooled into believing it has a reserved VMID
when in reality it doesn't, ultimately leading to GPU hangs when SPM is
used.

Fixes: 80e709ee6ecc ("drm/amdgpu: add option params to enforce process isolation between graphics and compute")
