Gabor Kaszab 545eab6d62 IMPALA-4826: Fix error during a scan on repeated root schema in Parquet. ...

Having the repetition level set to REPEATED on the root schema
resulted a scan to fail with error when Impala tried to parse that
table.

As a solution, the 'REPEATED' repetition level is ignored when the
root schema is processed. The reasoning behind is that the Parquet
format description says that the repetition level of the root schema
should not be set to REPEATED anyway, so it's safe to ignore it in
case it is set to this value for some reason.
