Fix the GPU bonded stream with 1 PP + 1 PME rank

WIth 1 PP + 1 PME rank the GpuBonded constructor gets passed the
non-local nonbonded stream which is nullptr and as a result the bonded
kernel launch happens in the default stream blocking concurrent
kernel execution.
This change makes sure that only when there is PP domain decomposition
is the GpuBonded constructor passed the nonlocal stream.

Fixes #3241
