Make DD setup obey PME restrictions
When running with many MPI ranks relative to the system size
combined with OpenMP, the domain decomposition could choose a setup
with to few PME grid lines per rank along x, which resulted in
a fatal error. Now the PME grid restrictions are checked during
the domain decomposition setup.
Fixes #2177.
