IMPALA-9060: make slow I/O logging less verbose

This avoids logging > 2 messages per scheduling quantum
with a slow I/O.

Testing:
Manually tested by adding a sleep and checking that the
error messages were as expected.

Also set max_chunk_size = 1024 to force the issue that
caused the log flooding before, confirmed that only
two errors were logged.
