bcachefs: Fix gap buffer bug in bch2_journal_key_insert_take()

Browse source

Multiple bug fixes for journal iters:

 - When the journal keys gap buffer is resized, we have to adjust the
   iterators for moving the gap to the end
 - We don't want to rewind iterators to point to the key we just
   inserted if it's not for the correct btree/level

Also, add some new assertions.
