BUG/MEDIUM: connection: Never cleanup server lists when freeing private conns

When a connection is released, depending on its state, it may be detached from
the session and it may be removed from the server lists. The first case may
happen for private or unsharable active connections. The second one should only
be performed for idle or available connections. We never try to remove a
connection from the server list if it is attached to a session. But it is also
important to never try to remove a private connecion from the server lists, even
if it is not attached to a session. Otherwise, the curr_used_conn server counter
is decremented once too often.

This bug was introduced by the commit 04a24c5ea ("MINOR: connection: don't check
priv flag on free"). It is related to the issue #881. It only affects the 2.3,
no backport is needed.
