Improve pair search thread load balance

With very small systems and many OpenMP threads, especially when
using GPUs, some threads can end up without pair search work. Better
load balancing reduces the pair search time. Also the CPU non-bonded
kernel time is slightly reduced in the extreme parallelization limit.
