Subject: [PATCH] [BUG] we could segfault during exit while freeing uri_auths

The following config makes haproxy segfault on exit :

defaults
	mode	http
	balance	roundrobin

listen  no-stats
        bind       :8001

listen  stats
        bind       :8002
	stats      uri /stats

The simple fix is to ensure that p->uri_auth is not NULL
before dereferencing it.
