GFS: fix bend_assoc_is_alive

When cs_get returns 0 the association is marked dead, rather then
being destroyed. If not, the session memory is being free'd before
the search/scan handler is finished. Also destroy request memory
in request_release rather than in various places, which resulted in
leaks from time to time.
