Subject: [PATCH] Fix kadmin addprinc -randkey -kvno
Commit f07bca9fc94a5cf2e3c0f58226c7973a4b86b7a9 made addprinc -randkey
use a single RPC request, but the server-side handling always creates
the random keys with kvno 1. If a kvno is specified in the RPC
request, set the kvno of the key data after creating it. Reported by
Andreas Ladanyi.
