If a socket is running a BPF_SK_SKB_SREAM_VERDICT program and KTLS is
enabled the data stream may be broken if both TLS stream parser and
BPF stream parser try to handle data. Fix this here by making KTLS
stream parser run first to ensure TLS messages are received correctly
and then calling the verdict program. This analogous to how we handle
a similar conflict on the TX side.
Note, this is a fix but it doesn't make sense to push this late to
bpf tree so targeting bpf-next and keeping fixes tags.
