Fix in-place shrinking huge reallocation purging bugs.
Fix the shrinking case of huge_ralloc_no_move_similar() to purge the
correct number of pages, at the correct offset. This regression was
introduced by 8d6a3e8321a7767cb2ca0930b85d5d488a8cc659 (Implement
dynamic per arena control over dirty page purging.).

This bug was introduced by 9673983443a0782d975fbcb5d8457cfd411b8b56
(Purge/zero sub-chunk huge allocations as necessary.).
