dlm: keep listening connection alive with sctp mode
The connection struct with nodeid 0 is the listening socket,
not a connection to another node. The sctp resend function
was not checking that the nodeid was valid (non-zero), so it
would mistakenly get and resend on the listening connection
when nodeid was zero.
