video: tegra: host: do not assume 3d channel opened by user space
- if user space does not open 3d channel, 3d scaling
algorithm is not initialized. so return safely when
3d scaling is disabled
- also do not call nvhost_module_suspend() explicitly
for host1x client modules. nvhost_channel_suspend()
takes care to suspend the module if ref count = 0
- call nvhost_module_suspend() only for host1x device
as it does not use actual hardware channel
