Change subject: IMPALA-5055: Fix DCHECK in parquet-column-readers.cc ReadPageHeader()
......................................................................


Patch Set 1:

Since we expect no performance penalty and consumers shouldn't rely on status being untouched,
can initialize it to OK() in GetBytes and do a private perf run to see whether it has a perf
impact? I think that would eliminate a potential cause for future problems.
