BUG/MINOR: acl: fix a double free during exit when using PCRE_JIT
When freeing ACL regex, we don't want to perform the free() in regex_free()
as it's already performed in free_pattern(). The double free only happens
when using PCRE_JIT when freeing everything during exit so it's harmless
but exhibits libc errors during a reload/restart.
Bug reported by Seri.
