xfs: Add the appropriate _require helper
1.xfs/162 uses xfs_db -c 'fuzz' but forgets to check if the feature
is supported. This will cause the case to fail on a system without
fuzz support. so we add _require to check if the fuzz is supported.
2.xfs/495 use _require_scratch_xfs_fuzz_fields to check the features
required by field fuzzing, but some of the features are not used in
this case like xfs_scrub, this will cause the case to skip on a system
without xfs_scrub support, even if the features being uesd are supported.
So we just need to use _require to check the features being used.
