From: Nikolay Borisov <nborisov@xxxxxxxx> commit 0f9c03d824f6f522d3bc43629635c9765546ebc5 upstream. Following commit f218ea6c4792 ("btrfs: delayed-inode: Remove wrong qgroup meta reservation calls") this function now reserves num_bytes, rather than the fixed amount of nodesize. As such this requires the same amount to be freed in case of failure. Fix this by adjusting the amount we are freeing.
