[BUG] User report getOffset not return right value.

[jiazhai]

Currently, After we create a partitioned topic, for a topic that has no producer/consumer created on it,
running command
bin/kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list 127.0.0.1:9092 --topic topic8 --time -1
will return
"Topic topic8 does not exist".
