s/dev_info/dev_dbg.

Also, since `dev_dbg` can be compiled out, the check performed on the
`VERS` tag existing is not guaranteed to be performed. We should
probably extract it out of the `dev_dbg` statement. This is true across
the series; which makes me think it might also benefit from a helper to
factor out the request_t.v/Tlv::new/dev_dbg common sequence.
