Tim Armstrong e148c1a7c3 IMPALA-6589: remove invalid DCHECK in parquet reader ...

The DCHECK was only valid if the Parquet file metadata is internally
consistent, with the number of values reported by the metadata
matching the number of encoded levels.

The DCHECK was intended to directly detect misuse of the RleBatchDecoder
interface, which would lead to incorrect results. However, our other
test coverage for reading Parquet files is sufficient to test the
correctness of level decoding.

Testing:
Added a minimal corrupt test file that reproduces the issue.
