Fix missing interactions with GPU and DD
Non-local LJ and Coulomb interactions would not be computed on a rank
after the non-local GPU pair-list was empty at some point in time;
either at the start of the run or during a run.
The issue is that the pair-list was initialized conditionally on
the size of the list in the device side data instead of the host side
data.
Although this could have led to silent errors for small step numbers,
most systems will likely crash for production runs.
Fixes #2502
