drm/amd/powerplay: don't give up if DPM is already running
Currently the driver crashes if smu7_enable_dpm_tasks() returns early, which it does if DPM is already active. It seems to be better just to continue anyway, at least I haven't noticed any ill effects. It's also unclear at what state the hardware was left by the previous driver, so IMO it's better to always fully initialize. Way to reproduce: with GPU passthrough. forced power off the VM or forced reset the VM without shutting down the Os.
