Nick Hill c2144c44a3 net/dns/resolver: update (*forwarder).forwardWithDestChan to always return an error unless it sends a response to responseChan ... We currently have two executions paths where (*forwarder).forwardWithDestChan returns nil, rather than an error, without sending a DNS response to responseChan. These paths are accompanied by a comment that reads: // Returning an error will cause an internal retry, there is // nothing we can do if parsing failed. Just drop the packet. But it is not (or no longer longer) accurate: returning an error from forwardWithDestChan does not currently cause a retry. Moreover, although these paths are currently unreachable due to implementation details, if (*forwarder).forwardWithDestChan were to return nil without sending a response to responseChan, it would cause a deadlock at one call site and a panic at another. Therefore, we update (*forwarder).forwardWithDestChan to return errors in those two paths and remove comments that were no longer accurate and misleading.
