Note new Changelog line!

It crashes with:

```
s32 field doesn't match size: expected 4, actual 8
```

Reported-by: @zerofeerouting
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Postgresql actually checks, and fails.

It's unclear why this field is an INTEGER (and u32) when it's a BIGINT 
in db here (it's an INTEGER in the channels table, just a BIGINT in the
channel_funding_inflights table).

ACK, I was wondering how this works on the sqlite site but it looks like sqlite integers are 8 bytes anyways...

extremely minor nit: technically it only breaks if you try to load inflights from a postgres db, which happens in the case that a channel open isn't resolved at startup
