dns: fix nameserver OOB read in IPv6-disabled fallback
In __res_msend_rc(), the IPv6-disabled fallback check uses conf->ns[nns]
inside a loop controlled by i, so it tests a fixed slot instead of
walking configured nameservers. This reads one past the array's size.
Use conf->ns[i] so the loop correctly detects whether all configured
nameservers are IPv6-only.
