Now that we block when enqueueing to the decryption queue, there is only one case in which we "drop" a inbound element, when decryption fails. We can use a simple, obvious, sync-free sentinel for that, elem.packet == nil. Also, we can return the message buffer to the pool slightly later, which further simplifies the code.
