Windows: not safe to dereference before locking

Windows: not safe to dereference before locking

Throughout cm_server.c, input parameters to functions that
are protected by cm_serverLock are dereferenced by assignment
during variable initialization prior to the cm_serverLock being
obtained.  As a result there is a race which can result in
either list corruption or dereferencing freed memory.
