Michael Tuexen 9f0abda051 Retire SCTP_WITH_NO_CSUM option. 
This option was used in the early days to allow performance measurements
extrapolating the use of SCTP checksum offloading. Since this feature
is now available, get rid of this option.
This also un-breaks the LINT kernel. Thanks to markj@ for making me
aware of the problem.
