[Needs Investigating] Possible lack of GPU synchronization if no Sommerfeld BCs #64

I think the GPU synchronization in the RHS evaluation loops are reliant on the implicit synchronization coming from the destruction of MFIter object in the Sommerfeld BCs loop. I think an explicit synchronization might be needed in the case of no Sommerfeld BCs.
