CVE-2023-52827

len is extracted from HTT message and could be an unexpected value in case errors happen, so add validation before using to avoid possible out-of-bound read in the following message iteration and parsing.

The same issue also applies to ppduinfo->ppdustats.common.num_users, so validate it before using too.

These are found during code review.

Compile test only.
