[PATCH] common/xfs: change _xfs_mkfs_validation_check return logic

[Zorro Lang <zlang@redhat.com>]

_xfs_mkfs_validation_check() try to make sure mkfs.xfs the stricter
input checks. It runs two test command lines with illegal parameters:

  $cmd -s size=2s
  $cmd -l version=2,su=260k

The current logic think if both of them return 0 (can't find
illegal input), then it means the current xfsprogs doesn't support
the stricter input checks.

But when test on machine with 4k sector size disk, the first command
will return non-zero, and then _xfs_mkfs_validation_check() return
non-zero to _require_xfs_mkfs_validation(). The latter will assume
xfsprogs support the stricter input checks.

So I think the proper logic should be if "any" of test command lines
return 0, then it means xfsprogs can't do stricter input test.
