Authentication application may be running and in the past
tried to probe driver (app_start) but unsuccessful. This
could be due to the bsg layer not ready to service the request.
On successful link up, driver will use the netlink Link Up
event to notify app to retry the app_start call.

In another case, app does not poll for new npiv host. This
link up event would notify app of the presence of a new SCSI Host.
