Unpoison Workspace Memory Before Freeing to Custom Free

MSAN is hooked into the system malloc, but when the user provides a custom
allocator, it may not provide the same cleansing behavior. So if we leave
memory poisoned and return it to the user's allocator, where it is re-used
elsewhere, our poisoning can blow up in some other context.
