commit 08ae0547e75ec3d062b6b6b9cf4830c730df68df upstream.
This patch fixes a double sock_release() call when the listen() is called for the dlm lowcomms listen socket. The caller of dlm_listen_for_all should never care about releasing the socket if dlm_listen_for_all() fails, it's done now only once if listen() fails.
