  Log:
  Restore queue depth settings across tag disable events.  The system often
  disables tag queuing temporarily in order to allow controllers a window
  to safely perform transfer negotiation with non-compliant devices.  Before
  this change, CAM would restore the queue depth to the controller specified
  maximum or device quirk level rather than any depth determined by reactions
  to QUEUE FULL/BUSY events or an explicit user setting.
  
  During device probe, initialize the flags field for XPT_SCAN_BUS.
  The uninitialized value often confused CAM into not bothering to
  issue an AC_FOUND_DEVICE async event for new devices.  The reason
  this bug wasn't reported earlier is that CAM manually announces
  devices after the initial system bus scans.
