Userspace can cause the kref to handles to increment
arbitrarily high. Ensure it does not overflow.

I signed off on this? Where? When? Are you sure?

The sign off was on the 4.4.y version that I cherry-picked this from.
There was a trivial conflict moving it to 4.9, but it did not modify any
changed lines, so I hadn't thought that was worth noting on the patch. I
apologise if leaving the signed-off-by was incorrect here.
