Change subject: IMPALA-5186: Handle failed CreateAndOpenScanner() in MT scan.
......................................................................


Patch Set 1:

I added an is_closed_ flag and DCHECK to make sure Close() is only called once.
Instead, I could check is_closed_ and return if you think that is preferable.

I prefer the DCHECK because there is only one thread working on a scanner,
and I don't see a compelling reason to support an idempotent Close() (why 
support a stronger guarantee than necessary?)

Please take another quick look.
