Don't divide space into strips smaller than the stencil size. #4

This triggered a vlasiator crash in a 4 × 4 cell test run with 4 nodes, where space was subdivided into 1 × 4 cell strips. These were too small for the stencil size of 2.

As an added bonus, this should speed up fsgrid setup for large simulations a little bit.

Looks sensible. Has it been tested with Thiago?

Let's wait with this one until the AMR dust settles in Vlasiator.
