VOL-4053: Fix Reenable of OLT following disable OLT and adapter restart.
- Allow event DeviceDownInd in state deviceStateConnected.
When the device is disabled it is in state deviceStateDown. When the
adapter is restarted in this state, the adapter comes back from restart
and establishes connection to OLT device and moves to deviceStateConnected.
However given the device was disabled prior to adapter going for
restart, it triggers a disable again for the device. The OLT
is already disabled, but acknowledges the disable command with
an down indication which translates to DeviceDownInd event
in the device FSM at adapter. Now this event should be allowed
in the FSM.
