[PATCH ocserv] Fix multiple session disconnect when max-same-clients is 0

[Kevin Cernekee]

max-same-clients is used to limit the number of outstanding sessions
(cookies).  If set to 0, it means an unlimited number of active cookies
can be owned by each user.  But it doesn't mean that the same cookie
can be reused for multiple CSTP connections with different IPs, as
the protocol does not normally work this way.
