This reverts commit 644d10716875b24388680925d6c7502420987bfe, upstream commit 6f8960541b1eb6054a642da48daae2320fddba93. The original patch for mainline, 6f8960541b1 (Btrfs: don't delay inode ref updates during log replay) lists 1d52c78afbb (Btrfs: try not to ENOSPC on log replay) as the only pre-3.18 dependency, but it also depends on 67de11769bd (Btrfs: introduce the delayed inode ref deletion for the single link inode), which was introduced in 3.14 and isn't in 3.12.y. The -stable commit added the check to btrfs_delayed_update_inode, which may look similar to btrfs_delayed_delete_inode_ref, but it's only superficial. The tops of both functions handle typical delayed node boilerplate. The upshot is that the patch is harmless since the caller already checks to see if we're doing log recovery, so we're not breaking anything. It should be reverted because it makes it appear as if this issue was fixed for users who did backport 67de11769bd, when it is not.
