    soc: ti: knav_qmss_queue: Fix PM disable depth imbalance in knav_queue_probe
    
    [ Upstream commit e961c0f19450fd4a26bd043dd2979990bf12caf6 ]
    
    The pm_runtime_enable will increase power disable depth. Thus
    a pairing decrement is needed on the error handling path to
    keep it balanced according to context.
