Lijun Pan be613736fd ibmvnic: add memory barrier to protect long term buffer ...

[ Upstream commit 42557dab78edc8235aba5b441f2eb35f725a0ede ]

dma_rmb() barrier is added to load the long term buffer before copying
it to socket buffer; and dma_wmb() barrier is added to update the
long term buffer before it being accessed by VIOS (virtual i/o server).
