bcachefs: Improve an insert path optimization

Browse source

The insert path had an optimization to short circuit lookup
table/iterator fixups when overwriting an existing key with the same
size value - but it was incorrect when other key fields
(size/version) were changing. This is important for the upcoming rework
to have extent updates use the same insert path as regular keys.
