From: Giovanni Cabiddu <[email protected]> When decompression falls back to deflate-generic after an analytics error, the request no longer completes through IAA. Move decompression byte accounting into the successful IAA completion path in both the synchronous and asynchronous flows so decomp_bytes only reflects bytes actually processed by IAA.
