rec-4.1.x: Try another worker before failing if the first pipe was full #7377

Short description

When the recursor is configured to distribute incoming queries to its worker threads itself, and in the unlikely case that the pipe to the selected thread is full, randomly select another worker to handle the query. If this one fails too, we give up.

Same PR than #7383 but for rel/rec-4.1.x.
