ASoC: Intel: Skylake: Fix DSP core ref count for init failure

Browse source

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.
