This patch simply checks is we got a null value from the map, and if so, throws
UnavailableException.

> When upgrading from 1.0 to 1.1, we observed that
> DatacenterSyncWriteResponseHandler.assureSufficientLiveNodes() can throw an
> NPE if one of the writeEndpoints has a DC that is not listed in the keyspace
> while one of the nodes is down. We observed this while running in EC2, and
> using the Ec2Snitch. The exception typically was was brief, but a certain
> segment of writes (using EACH_QUORUM) failed during that time.
> This ticket will address the NPE in DSWRH, while a followup ticket will be
> created once we get to the bottom of the incorrect DC being reported from
> Ec2Snitch.
