IMPALA-5031: Fix use of uninitialised var in SendTopicUpdate()
When SendTopicUpdate() returns an error, it does not set update_skipped,
so the variable is uninitialised. This means that the duration between
topic updates will depend on the uninitialised value.

> builds are supported after https://gerrit.cloudera.org/#/c/6186/, but
> Impala's test suite triggers many errors under UBSAN. Those errors should be
> fixed and then there should be a way to run the test suite under UBSAN and
> fail if there were any errors detected.
