ocean_only benchmark, global_ALE/* and global contain memory errors

[nichannah]

This may be a duplicate of #298
Benchmark, global_ALE/* and global tests complete successfully but appear to be using uninitialised memory. This could well be a problem within the Valgrind MPI wrappers, but appears before a model crash in #298.

These are due to a bug in the Valgrind MPI wrappers which has been fixed in the latest version. I'll close this issue once I've confirmed that the errors have gone away.
