crypto: iaa - avoid counting fallback decompression bytes

Browse Source 
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.
