    ASoC: SOF: core: Ensure sof_ops_free() is still called when probe never ran.
    
    [ Upstream commit f549a82aff57865c47b5abd17336b23cd9bb2d2c ]
    
    In an effort to not call sof_ops_free twice, we stopped running it when
    probe was aborted.
    
    Check the result of cancel_work_sync to see if this was the case.
    
    Fixes: 31bb7bd9ffee ("ASoC: SOF: core: Only call sof_ops_free() on remove if the probe was successful")
