    AHCI - Port Multiplier bug fixes
    
    * The error ccb must be used in ahci_pm_softreset() to collect a reliable
      signature from the device.
    
    * Release the error ccb before performing any ahci_pm_*() functions (which
      have to issue their own commands).
    
    * Probe the CAM bus asynchronously.
    
    * Proactively assert that the error ccb is not used in a reentrant fashion.
