tls: decrement decrypt_pending if no async completion will be called

Browse source

[ Upstream commit f7fa16d498 ]

With mixed sync/async decryption, or failures of crypto_aead_decrypt,
we increment decrypt_pending but we never do the corresponding
decrement since tls_decrypt_done will not be called. In this case, we
should decrement decrypt_pending immediately to avoid getting stuck.

For example, the prequeue prequeue test gets stuck with mixed
modes (one async decrypt + one sync decrypt).
