gpu: nvgpu: bail out from poweroff if channel suspend fails
During gk20a_pm_prepare_poweroff(), if call to gk20a_channel_suspend()
fails, we proceed to disable other components and then return error.
But when genpd sees the error, it will abort the suspend sequence and
keep the device state as active.
But since we have already disabled all the components, GPU lands in
invalid state.
Hence, if channel_suspend() fails then do not proceed but return
the error immediately
