[PATCH 4/9] selftests/mm: mremap_test: correct multiple VMA range size

[Sarthak Sharma]

In the test mremap_move_multiple_vmas(), pages 4
to 6 form a single VMA. But the helper function
is_multiple_vma_range_ok() checks pages 4 and 5 as
one range and treats page 6 separately.

Check all three pages as a single range and skip
the page 6 iteration to match the actual VMA layout.

Fixes: d53f248258e1 ("tools/testing/selftests: extend mremap_test to test 
multi-VMA mremap")
