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.
