Fix excessive list splitting
Due to a possible integer overflow, the pair list splitting code could
end up over-splitting pair lists and causing large performance
degradation. Due to the larger processor count, runs using AMD GPUs,
using 100k+ simulation systems are more prone to suffer from the issue.
Fixes #1904
