[PATCH v2 07/42] vpn: Check if connecting when setting state or disconnecting

Add checking of connected and connecting state in cases when the state
is being set and state transitions to disconnecting. This change avoids
clearing the transport ident when VPN is waiting for input from VPN
agent (association state).
