[PATCH] common/fuzzy: don't attempt online scrubbing unless supported

[Anthony Iliopoulos <ailiop@suse.com>]

Many xfs metadata fuzzing tests invoke xfs_scrub to detect online errors
even when _scratch_xfs_fuzz_metadata is invoked with "offline". This
causes those tests to fail with output mismatches on kernels that don't
enable CONFIG_XFS_ONLINE_SCRUB. Bypass scrubbing when not supported.
