Today if we run fsr and crash, log replay can fail because the recovery code tries to instantiate the donor inode from disk to replay the swapext, but it's been deleted and we get verifier failures when we try to read it off disk with i_mode == 0. Strip the extent owner changes out of the logged fields when we're freeing the inode to avoid this.
