btrfs: release metadata before running delayed refs



commit f45c752b65af46bf42963295c332865d95f97fff upstream.

We want to release the unused reservation we have since it refills the
delayed refs reserve, which will make everything go smoother when
running the delayed refs if we're short on our reservation.
