[ Upstream commit 2c9a266afefe137bff06bbe0fc48b4d3b3cb348c ]

When running small packets [length < 256 bytes] traffic, packets were being dropped due to invalid data in those packets which were delivered by the driver upto the stack. Using pci_dma_sync_single_for_cpu ensures copying latest and updated data into skb from the receive buffer.
