tg3: Fix INTx fallback when MSI fails
tg3: Fix INTx fallback when MSI fails MSI setup changes the value of irq_vec in struct tg3 *tp. This attribute must be taken into account and restored before we try to do a new request_irq for INTx fallback. In powerpc, the original code was leading to an EINVAL return within request_irq, because the driver was trying to use the disabled MSI virtual irq number instead of tp->pdev->irq.
