At the initial stage of the PME load balancing the domain decomposition dynamic load balancing can make cells smaller than the cut-off. This could potentially lead to missing interaction during a very limited number of steps. But this bug mainly reduces the effectiveness of the PME load balancing

fixed bug with DD cut-off check and PME DLB

During the initial stage of PME DLB, the cut-off limit check for the
DD DLB was not checked correcty. This reduced the effectiveness of
both DD and PME DLB and could lead to missing interactions during
a very limited number of steps.
Fixes #1169
