    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.
