[PATCH] xfs/119: fix too small log size error

[Zorro Lang <zlang@redhat.com>]

xfs/119 fails on 4k hard sector size device if reflink (with/without
rmapbt) is enabled:

  # mkfs.xfs -f -m reflink=1,rmapbt=0 -l version=2,size=2560b,su=64k /dev/sdf
  log size 2560 blocks too small, minimum size is 2688 blocks
  # mkfs.xfs -f -m reflink=1,rmapbt=1 -l version=2,size=2560b,su=64k /dev/sdf
  log size 2560 blocks too small, minimum size is 4368 blocks

So remove log size parameter and run mkfs.xfs again if it fails.

I saw Dave changed the log size once in commit:
  d0a3cc5a xfs/104: log size too small for 4k sector drives

But it's still not enough after we have reflink feature now. I don't
know why this case need "-l version=2,size=2560b,su=64k",
if someone learns about this case, please tell me how to change this
case properly. If the log size parameter is not necessary, I'd like
to remove it.

Thanks,
Zorro
