_fini() returns an error, the ep will be dereferenced (refcnt=1). Then rx_data() calls c4iw_ep_disconnect() which starts the close operation. But if send_halfclose() fails in c4iw_ep_disconnect(), we will call release_ep_resources() derefing the ep which reduces the refcnt to 0 and and frees the ep. However we still has the ep mutex at that point, so we have a touch-after-free bug. There is a similar issue where peer_close() calls c4iw_ep_disconnect(). The solution is to add a reference to the ep in c4iw_ep_disconnect() after acquiring the mutex, and release it after releasing the mutex.
