dnsdist: Fix a race when a cross-protocol query triggers an IO error

[rgacogne]

Short description

The IO error was not always handled by the proper TCP thread, possibly leading to a race condition where two TCP worker threads were touching the same TCP connection object at the same time.
Technically the issue also exists for XFR responses, but these are very unlikely to cross protocols. We are still applying the same fix.

The issue was introduced in 516a000.

This was reported by Thread Sanitizer:
