Btrfs: Fix async thread shutdown race It was possible for an async worker thread to be selected to receive a new work item, but exit before the work item was actually placed into that thread's work list. This commit fixes the race by incrementing the num_pending counter earlier, and making sure to check the number of pending work items before a thread exits.
