 @Function      PvzServerOnVmOffline
 @Description   The VM manager calls this when a guest VM machine is about to
                go offline. The VM manager might have unmapped the GPU kick
                register for such VM but not the GPU memory until the call
                returns. Once the function returns, the FW does not hold any
                reference for such VM and no workloads from it are running in
                the GPU and it is safe to remove the memory for such VM.
 @Return        PVRSRV_OK on success. PVRSRV_ERROR_TIMEOUT if for some reason
                the FW is taking too long to clean-up the resources of the
                OSID. Otherwise, a PVRSRV_ERROR code.
