sctp: delete the nested flexible array payload

This patch deletes the flexible-array payload[] from the structure
sctp_datahdr to avoid some sparse warnings:

  # make C=2 CF="-Wflexible-array-nested" M=./net/sctp/
  net/sctp/socket.c: note: in included file (through include/net/sctp/structs.h, include/net/sctp/sctp.h):
  ./include/linux/sctp.h:230:29: warning: nested flexible array

This member is not even used anywhere.
