With NetworkManager, an 802.1x or MACSEC connection with no secrets will never time out.

Issue

• An 802.1x connection profile never times out and appears stuck waiting for auth even though no secrets are required.

• The logs show NetworkManager is waiting for secrets, immediately after logging that none are required:

  Mar 01 14:58:20  <info>  device (eth0): state change: config -> need-auth (reason 'none') [50 60 0]
  Mar 01 14:58:20  <info>  device (eth0): Cleared secrets, but setting didn't need any secrets.
