CVE-2019-8912 was assigned for a use-after-free vulnerability in the AF_ALG
implementation. However, that issue affects additional network families and now
there is a more generic fix available.

Since we have already applied the AF_ALG fix, it is worth noting that it is fine to have the AF_ALG fix and this more generic fix both applied.

Clean cherry pick of the fix. I smoke tested a kernel build in a Bionic VM.
