The Zstd context mempool can reuse buffers that were previously poisoned under AddressSanitizer, leading to false-positive use-after-poison reports during zloop and other stress tests. Explicitly unpoison memory when handing buffers out to Zstd and poison the user-visible region again when buffers are returned to the pool. This makes the allocator ASan-correct while preserving existing pooling behavior. Also fix non-standard void * pointer arithmetic in zstd_free() and remove an early return in zstd_dctx_alloc() so kmem_type/kmem_size are always set on pool hits. This only affects ASan bookkeeping in user space, does not change runtime behavior in non-ASan configurations, and does not affect on-disk formats.
