Each completion ring entry has a valid bit to indicate that the entry
contains a valid completion event. The driver's main poll loop
__bnxt_poll_work() has the proper dma_rmb() to make sure the valid
bit of the next entry has been checked before proceeding further.
But when we call bnxt_rx_pkt() to process the RX event, the RX
completion event consists of two completion entries and only the
first entry has been checked to be valid. We need the same barrier
after checking the next completion entry. Add missing dma_rmb()
barriers in bnxt_rx_pkt() and other similar locations.
