[SPARK-16740][SQL] Fix Long overflow in LongToUnsafeRowMap
## What changes were proposed in this pull request?
Avoid overflow of Long type causing a NegativeArraySizeException a few
lines later.
## How was this patch tested?
Unit tests for HashedRelationSuite still pass.
I can confirm the python script I included in
https://issues.apache.org/jira/browse/SPARK-16740 works fine with this patch.
Unfortunately I don't have the knowledge/time to write a Scala test case for
HashedRelationSuite right now. As the patch is pretty obvious I hope it can be
included without this.
Thanks!
