refs/reftable: reload correct stack when creating reflog iter

When creating a new reflog iterator, we first have to reload the stack
that the iterator is being created. This is done so that any concurrent
writes to the stack are reflected. But `reflog_iterator_for_stack()`
always reloads the main stack, which is wrong.

Fix this and reload the correct stack.
