you are expected to enable specific flags in each balancing module that support
it. For example, ip_hash module doesn't support 'backup' flag and thus does
not set 'NGX_HTTP_UPSTREAM_BACKUP' in ngx_http_upstream_ip_hash().

I suggest that you have specified something different from the default balancer
and thus got this error, since your patch doesn't allow this parametr in it.
