From: Alexander Aring <aahringo@xxxxxxxxxx>
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.
