Fix KDC to drop repeated in-progress requests

When a KDC receives a repeated request while the original request is
still in progress, it is supposed to be to drop the request. Commit
f07760088b72a11c54dd72efbc5739f231a4d4b0 introduced a bug in this
logic, causing the KDC to instead send an empty reply. In
kdc_check_lookaside(), return a NULL reply_packet for empty entries,
restoring the expected behavior.
