    IKEv2: re-instate NO_PROPOSAL_CHOSEN when we do not find any connection
    
    As per feedback from the IPSEC WG:
    
    Tero said:
    
    	If both implementations work correctly you should NEVER send
    	INVALID_SYNTAX error. That always means there is programming
    	error in one of the implementations.
    
    	[...]
    
    	We discussed this, but decided that we want to keep error
    	codes limited, not to leak out information what is wrong in
    	the configuration. So you get same NO_PROPOSAL_CHOSEN error
    	notification regardless whether your algorithm list does not
    	match, or whether the ip is unknown, or whether the identity of
    	the other end is unknown.
