When CONFIG_XFS_FS=y and xfsprogs is missing, mkfs.xfs and mount both fail, but SPLIT_HUGE_PAGE_TEST_XFS_PATH is assigned from mktemp -d and stays set. The test then runs against plain tmpfs and six subtests fail. The script already has a skip path for this test, but it never runs because the path variable is always set. Assign SPLIT_HUGE_PAGE_TEST_XFS_PATH only once mkfs.xfs and mount have both succeeded, and remove the image and directory otherwise.
