Lars Volker a377f28543 IMPALA-6927: Remove invalid DCHECK from coordinator backend state ...

An invalid DCHECK in Coordinator::BackendState::InstanceStatsToJson()
assumed that the number of fragment instances is equal to the number of
fragments. This is not true when mt_dop > 0, which results in multiple
instances of a fragment on a single node.

The fix is to remove the invalid DCHECK. It served to document the
programmers understanding and the code does not rely on the assumption
being true.

This change adds a test that would fail with the DCHECK in place.
