Update description of net.sctp.sctp_rmem and net.sctp.sctp_wmem tunables 



sctp does not use second and third ("default" and "max") values
of sctp_rmem tunable. The format is the same as tcp_rmem
but the meaning is different so make the documentation explicit to
avoid confusion.

sctp_wmem is not used at all.
