[PATCH v2 4/4] xfs/21{6,7} Use default -l concurrency=0 on mkfs.xfs that supports it

[Lukas Herbolt <lukas@herbolt.com>]

The XFS concurrency optimization breaks the log sizing check on
systems with non-rotational disks and high amount of CPUs. Default to
the old behavior with -l concurrency=0 and with -d concurrency=0.
