dlm: set zero linger time on sctp socket
The recovery time for a failed node was taking a long time because the failed node could not perform the full shutdown process. Removing the linger time speeds this up. The dlm does not care what happens to messages to or from the failed node. Signed-off-by: Dongmao Zhang <dmzhang@suse.com> Signed-off-by: David Teigland <teigland@redhat.com>
