sctp: correct bounds check in sctp_setsockopt_auth_key
[ Upstream commit 328fc47ea0bcc27d9afa69c3ad6e52431cadd76c ]
The bonds check to prevent buffer overlflow was not exactly
right. It still allowed overflow of up to 8 bytes which is
sizeof(struct sctp_authkey).
Since optlen is already checked against the size of that struct,
we are guaranteed not to cause interger overflow either.
