Removes PME rank dependency on Non-local X H2D copy when  buffer ops are on GPU but, Halo exchange happens over host-MPI.

This was not a problem until now because because !stepWork.haveGpuPmeOnThisRank will always evaluate to true in case of domain decomposition as PME will always be on a separate rank.
But now with PME decomposition this bug gets exposed.
