[ Upstream commit 4d42cd6bc2ac1b9be50ade13771daec90c9d18b1 ]
Gaurav reports that TLS Rx is broken with async crypto accelerators. The commit under fixes missed updating the retval byte counting logic when updating how records are stored. Even tho both before and after the change 'decrypted' was updated inside the main loop, it was completely overwritten when processing the async completions. Now that the rx_list only holds non-zero-copy records we need to add, not overwrite.
