CGNR iterative solver with -no_reduced_fft fails miserably in MPI mode #174

I have accidentally found this bug while running automatic tests. It is present 
down to at least v.0.78 (the earliest Windows MPI executable that is available).

However, the combination of parameters is rather weird to seriously worry about.

r1263 adds an explicit exception for this case. However, making such a weird 
combination operational requires significant effort - rearranging of memory 
distribution memory distribution should be changed to have both x and gridX-x 
on the same processor. This is of low priority.
