[PATCH 07/13] xfstest: enable xfs_repair for large filesystem testing

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

Now that large filesystem testing does not play free space games to
fill the space without IO, we can enable xfs_repair when running in
this mode. xfs_repair has had it's scalability problems solved, too,
so this is a safe thing to do.
