tools/testing/scatterlist: Fix overflow of max segment size

[ Upstream commit 96667052149da3855c4361925324b690c687152f ]

Because SCATTERLIST_MAX_SEGMENT was removed and replaced with UINT_MAX,
the test overflows the max_sgement variable. Remove this case.

Fixes: 7a60c2dd0f57 ("drm: Remove SCATTERLIST_MAX_SEGMENT")
