bugfix ZookeeperShardState:IOException is never thrown

[nmatsui]

ZookeeperSharedState can't be compiled because it has unnecessary try-catch clause.

Hi nmatsui, I fixed that, doing the following

 git diff origin/master -- /home/christian/Git/kinesis-storm-spout/src/main/java/com/amazonaws/services/kinesis/stormspout/state/zookeeper/ZookeeperShardState.java
