[PATCH BlueZ] mesh: Allow to finish key refresh when no AppKeys are stored

[Inga Stotland <inga.stotland@intel.com>]

This handles a case when a Key Refresh procedure is in place with
no application keys stored in the keyring. When KR procedure is
finalized, the check for the presence of AppKeys storage directory
does not return failure if the directory does not exist.

Also, remove duplicate include.
