wifi: handle transition disable indication in ConnectingOrConnectedState

Currently transition disable indication getting handled only in
L2ConnectingState. But transition disable indication getting ignored
if network state changed event reported to framework before transition
disable indication due to state machine moving to L2ConnectedState.

Fix this by handling transition disable indication in
ConnectingOrConnectedState
