[PATCH v2] xfs/032: test the next block size if mkfs fails

[Zorro Lang <zlang@redhat.com>]

If test on a 512b sector size device, xfs/032 will try to do:

  mkfs.xfs -s size=512 -b size=512 ...

The 512b block size is not acceptable for V5 XFS. So if mkfs.xfs
fails, try next block size (blksize *= 2) directly.

Signed-off-by: Zorro Lang <zlang@redhat.com>

V1 try to find the minimum acceptable block size at first, V2 drop
that method, and then *continue* the test if _scratch_mkfs return
error.

Thanks,
Zorro
