[PATCH net-next 3/7] sctp: export some functions for sctp_diag in inet_diag

[Xin Long <lucien.xin@gmail.com>]

inet_diag_msg_common_fill is used to fill the diag msg common info,
we need to use it in sctp_diag as well, so export it.

We also add inet_diag_get_handler() to access inet_diag_table in sctp
diag.
