net: ena: xdp: update napi budget for DROP and ABORTED
This patch fixes two issues with XDP: 1. If the XDP verdict is XDP_ABORTED we break the loop, which results in us handling one buffer per napi cycle instead of the total budget (usually 64). To overcome this simply change the xdp_verdict check to != XDP_PASS. When the verdict is XDP_PASS, the skb is not expected to be NULL. 2. Update the residual budget for XDP_DROP and XDP_ABORTED, since packets are handled in these cases.
