drm/tests: Fix incorrect argument in drm_test_mm_insert_range

Browse Source 
While drm_mm test was converted form igt selftest to kunit, unexpected
value of "end" argument equal "start" was introduced to one of calls to a
function that executes the drm_test_mm_insert_range for specific start/end
pair of arguments.  As a consequence, DRM_MM_BUG_ON(end <= start) is
triggered.  Fix it by restoring the original value.
