Fix a couple of documentation problems in app_queue.c

Fix a couple of documentation problems in app_queue.c

* The RemoveQueueMember app made mention of options that could
be passed in, but no options are supported. I have removed the
listing of options from the documentation.

* The RQMSTATUS variable did not list "NOTDYNAMIC" as a possible
value that could be set.
