lib-index: mail_index_sync_map() - Don't try to-resync extension updates
This was done to call extension record sync handlers, but the previous
commit removes them. Fixes a problem where obsolete cache offsets were
used in some situations:
- Some cache updates are from external transactions and some are from
non-external transactions. This is because cache offset updates are being
added by whatever the parent index transaction is.
- When mail_index_sync_map() is mapping MAIL_INDEX_SYNC_HANDLER_FILE, it
has already synced the map. But it's calling mail_index_sync_record()
for non-external transactions to call expunge handlers and extension
update handlers. It's calling the regular mail_index_sync_record() to do
this work.
- But mail_index_sync_record() is actually still updating the map. So now
mail_index_sync_record() is called for all non-external cache updates,
but not for external cache updates! And since these are somewhat
randomly either external or non-external, the end result is that the
cache offset may be obsolete.
