Fix spin-loop bug in k5_sendto_kdc
In the second part of the first pass over the server list, we passed
the wrong list pointer to service_fds, causing it to see only a subset
of the server entries corresponding to sel_state. This could cause
service_fds to spin if an event is reported on an fd not in the
subset.
