ASoC: SOF: sof-audio: Fix DSP core put imbalance on widget setup failure

In case the widget setup fails we should only decrement the core usage
count if the sof_widget_free_unlocked() has not been called as part of
the error handling.
sof_widget_free_unlocked() calls snd_sof_dsp_core_put() and the additional
core_put will cause imbalance in core usage count.
Use the existing use_count_decremented to handle this issue.
