[Mpi3-rma] Disp_unit in allocate_shared should be returned by win_shared_query?

Hi Torsten,

Is one process' disp_unit meaningful at another process?  I thought that 
this is not the case.  MPI provides no other routines to query another 
process' disp_unit.

Also, what meaning does a disp_unit have in the context of load/store 
operations that will result from win_shared_query?

Maybe I'm missing something, but this doesn't seem necessary.
