Use short lived pool to avoid memory leaks

Remove the comment about binding upstream and downstream connections. It
seems to be obsolete since r104604, r104605, r105108.

Also avoid allocating memory if we are not handling the connection.

mod_proxy_balancer: Restore balancing after a failed worker has
recovered when using lbmethod_bybusyness.

PR: 48735

Markus Stoll and Adam C both submitted patches against 2.2.x
to bug 48735.  Compared with those two, this solution

1. resets the busy field in the error-ed worker at the end of
   the request instead of at recovery time
2. leaves the lbstatus field alone
3. covers all possible scenarios where the busy field in the
   error-ed worker needs to be adjusted, since a cleanup to
   perform the decrement is registered at the point of the
   increment
