Orders API: Fix race condition in voucher redemption (Z#23230391)

The old code relied on the `Voucher.redeemed` value obtained *before*
the lock was taken, not afterwards.

The change in services/orders.py is functionally pointless, but it makes
the pattern of "fill availability only after lock" clearer and might
avoid introducing similar bugs in the future.
