When support for dynamic names was added for use_backend rules in
702d44f2f ("MEDIUM: proxy: support use_backend with dynamic names"), the
sample expression resulting from parse_logformat_string() was only freed
for non dynamic rules (when the expression resolved to a simple string
node). But for complex expressions (ie: multiple nodes), rule->dynamic
was set but the expression was never released, resulting in a small
memory leak when freeing the parent proxy.
To fix the issue, in free_proxy(), we free the switching rule expression
if the switching rule is dynamic.
This should be backported to every stable versions.
[ada: prior to 2.9, free_logformat_list() helper did not exist: we may
use the same manual sample expr freeing logic as in server_rules pruning
right above it]
