    AHCI - Try to salvage port on PM target failure.
    * If a PM target times out disable it, but try to salvage the rest of
      the port so other PM targets continue to operate.  We do this by
      stopping the port, issuing a CLO, and then restarting it to clear
      the BSY condition, then re-issue whatever commands might have been
      active (probably none if this is a PM since we are restricted to
      one command at a time).
