btrfs: fix locking when we put back a delayed ref that's too new
commit d0280996437081dd12ed1e982ac8aeaa62835ec4 upstream.
In __btrfs_run_delayed_refs, when we put back a delayed ref that's too
new, we have already dropped the lock on locked_ref when we set
->processing = 0.
This patch keeps the lock to cover that assignment.
Fixes: d7df2c796d7 (Btrfs: attach delayed ref updates to delayed ref heads)
