Subject: bna: fix interrupts storm caused by erroneous packets

From: Ivan Vecera <[email protected]>

[ Upstream commit ade4dc3e616e33c80d7e62855fe1b6f9895bc7c3 ]

The commit "e29aa33 bna: Enable Multi Buffer RX" moved packets counter increment from the beginning of the NAPI processing loop after the check for erroneous packets so they are never accounted. This counter is used to inform firmware about number of processed completions (packets). As these packets are never acked the firmware fires IRQs for them again and again.
