This avoids a problem where a Linux client advertises a callback path that doesn't work, due to a firewall, and then times out an Open attempt before the FreeBSD server gives up its callback connection attempt. (Suggested by drb at karlov.mff.cuni.cz.) The server should probably have a 1sec timeout on callback connection attempts when there are no delegations issued to the client, but that patch will require changes to the krpc and this serves as a work around until then.
