I've been seeing confusing superblock transactions in logprint, this is
an attempt to resolve them and make debugging misc buffer updates easier.

Before

$ xfs_logprint -o xfs.image
----------------------------------------------------------------------------
Oper (2): tid: c32589f8  len: 24  clientid: TRANS  flags: none
BUF:  #regs: 2   start blkno: 0 (0x0)  len: 1  bmap size: 1  flags: 0x9000
Oper (3): tid: c32589f8  len: 384  clientid: TRANS  flags: none
SUPER BLOCK Buffer:
icount: 6360863066640355328  ifree: 262144  fdblks: 0  frext: 0
----------------------------------------------------------------------------

After

$ xfs_logprint -o xfs.image
----------------------------------------------------------------------------
Oper (2): tid: c32589f8  len: 24  clientid: TRANS  flags: none
BUF:  #regs: 2   start blkno: 0 (0x0)  len: 1  bmap size: 1  flags: 0x9000
Oper (3): tid: c32589f8  len: 384  clientid: TRANS  flags: none
