[PATCH net 2/3] ibmvnic: remove unnecessary rmb() inside ibmvnic_poll

[Lijun Pan]

rmb() was introduced to load rx_scrq->msgs after calling
pending_scrq(). Now since pending_scrq() itself already
has dma_rmb() at the end of the function, rmb() is
duplicated and can be removed.

Fixes: ec20f36bb41a ("ibmvnic: Correctly re-enable interrupts in NAPI polling 
routine")
