Fix a couple of minor issues with IOR output

This commit fixes two issues:

 - The AIO backend prints the max outstanding transactions when starting. This is printed by every MPI rank and doesn't add much. Probably is left over from some debugging.

 - Init MPI ***before*** parsing the command line. Without this every rank thinks it is rank 0 so messages that should only be printed by rank 0 are printed n times.
