Fixes issue in RAJA scan tests when the length of the array is 0.

@davidbeckingsale thanks for the quick fix. It would be helpful if we could check things like this with some CI tests on GitHub. I guess that means we should work on getting the Gitlab CI stuff working for RAJA....

Thanks @davidbeckingsale, my only quibble is that the check for null before free is unnecessary. Just like regular free it's guaranteed to do that check internally.

[davidbeckingsale]

Got it, fixed @trws.

As soon as travis comes back green, I'll merge, thanks again @davidbeckingsale!

Note that this will require bumping RAJA's camp tpl, and also removing a bugfix left in the StaticLayout header.

Thanks for the quick fix guys. I'll put up a PR to update the camp version in RAJA to this.
