Description of problem:
When asking for help for 'qpid-config --passive' we get:
[root@rhel6i ~]$ qpid-config --help | grep -A 3 passive
    --passive, --dry-run
                        Do not actually add the exchange or queue, ensure that
                        all parameters and permissions are correct and would
                        allow it to be created.


Actually it should report statement from this PDF instead:
http://www.amqp.org/confluence/download/attachments/720900/amqp.0-10.pdf
'If set, the server will not create the exchange. The client can use this to check whether an exchange
exists without modifying the server state.'

Because this is what this command does:
Does the queue qname_test exists?
[root@rhel6i ~]$ qpid-config add queue qname_test --durable --passive
Failed: SessionException: ExecutionException(error_code=404, command_id=serial(81), class_code=8, command_code=1, field_index=0, description=u'not-found: Queue not found: qname_test (qpid/broker/SessionAdapter.cpp:686)', error_info={}, channel=1, id=serial(93))
ecode=1

No queue qname_test doesn't exist. So create queue:
[root@rhel6i ~]$ qpid-config add queue qname_test --durable
ecode=0

Does the queue qname_test exist now? 
[root@rhel6i ~]$ qpid-config add queue qname_test --durable --passive
ecode=0

Yes queue exist.

Version-Release number of selected component (if applicable):

How reproducible:
100%

Steps to Reproduce:
1. qpid-config --help | grep -A 3 passive
2. qpid-config add queue qname_test --durable --passive
3. qpid-config add queue qname_test --durable
4. qpid-config add queue qname_test --durable --passive
  
Actual results:
[root@rhel6i ~]$ qpid-config --help | grep -A 3 passive
    --passive, --dry-run
                        Do not actually add the exchange or queue, ensure that
                        all parameters and permissions are correct and would
                        allow it to be created.

Expected results:
[root@rhel6i ~]$ qpid-config --help | grep -A 3 passive
    --passive, --dry-run
                        If set, the server will not create the exchange. 
			The client can use this to check whether an exchange
			exists without modifying the server state.
