During dsp init failure, the ref count is not incremented and dsp is powered down. But as the skl driver calls put_core for the init failure it decrements the dsp core ref count and ref count becomes unbalanced.
This results in dsp core powered up in further runtime suspend/resume cycles and never powered down.
So increment the ref count before dsp core powerup and for any failure, decrement in put_core will be balanced.
