crimson/os/seastore/transaction_manager: fix delayed alloc addr in rewrite_logical_extent

Setting nlextent's to the addr of the original extent violates invariants
in the intrusive_set we're using for ExtentIndex and generally breaks the
assumption in cache that paddrs are unique until reuse.  This means we'll
do an extra update_mapping for now -- we can refactor SegmentCleaner to
avoid it later.
