dlm: reject SCTP configuration if not enabled 



Reject SCTP dlm configuration if the kernel was never build with SCTP.
Currently the only one known user space tool "dlm_controld" will drop an
error in the logs and getting stuck. This behaviour should be fixed to
deliver an error to the user or fallback to TCP.
