Merge branch 'tls-rx-follow-ups-to-rx-work'

Jakub Kicinski says:

====================
tls: rx: follow ups to rx work

A selection of unrelated changes. First some selftest polishing.
Next a change to rcvtimeo handling for locking based on an exchange
with Eric. Follow up to Paolo's comments from yesterday. Last but
not least a fix to a false positive warning, turns out I've been
testing with DEBUG_NET=n this whole time.
