Subject: [PATCH net-next 08/11] sctp: remove the typedef sctp_supported_ext_param_t

This patch is to remove the typedef sctp_supported_ext_param_t, and
replace with struct sctp_supported_ext_param in the places where it's
using this typedef.

It is also to use sizeof(variable) instead of sizeof(type).
