IMPALA-2988: Refactor HdfsTableSink::Close() so that it cannot fail

HdfsTableSink::Close() makes calls to functions that can fail with a
Status. However, since the function has a void return type, these
error statuses are just logged and we cannot take any action according
to the type of error.

This patch moves the closing of the partition file into the FlushFinal
function from Close(), so that in case of an error on closing the
file, the error is propagated up and some action can be taken.

Also fixed some long lines in this patch.
