sctp: add param size validation for SCTP_PARAM_SET_PRIMARY
commit ef6c8d6ccf0c1dccdda092ebe8782777cd7803c9 upstream.
When SCTP handles an INIT chunk, it calls for example:
sctp_sf_do_5_1B_init
sctp_verify_init
sctp_verify_param
sctp_process_init
sctp_process_param
handling of SCTP_PARAM_SET_PRIMARY
sctp_verify_init() wasn't doing proper size validation and neither the
later handling, allowing it to work over the chunk itself, possibly being
uninitialized memory.
