xfs/122: add tests for commitrange structures

Update this test to check the ioctl structure for XFS_IOC_COMMIT_RANGE,
which was added in 6.12.  This will be the last ever addition to
xfs/122, because in 6.13 we moved the ondisk structure checks to libxfs
after which we'll be able to _notrun this test on newer codebases.
