bnx2: Don't receive packets when the napi budget == 0
Processing any incoming packets with a with a napi budget of 0 is incorrect driver behavior. This matters as netpoll will shortly call drivers with a budget of 0 to avoid receive packet processing happening in hard irq context. Signed-off-by: "Eric W.
