In protocol_bind_all() (involved in startup sequence):
We only free errmsg (set by fam->bind() attempt) when we make use of it.
But this could lead to some memory leaks because there are some cases
where we ignore the error message (e.g: verbose=0 with ERR_WARN messages).
As long as errmsg is set, we should always free it.
As mentioned earlier, this really is a minor leak because it can only occur on
specific conditions (error paths) during the startup phase.
This may be backported up to 2.4.

Backport notes:
-> 2.4 only:
Replace this:
| ha_warning("Binding [%s:%d] for %s %s: %s\n",
| listener->bind_conf->file, listener->bind_conf->line,
| proxy_type_str(px), px->id, errmsg);
By this:
| else if (lerr & ERR_WARN)
| ha_warning("Starting %s %s: %s\n",
| proxy_type_str(px), px->id, errmsg);
