tg3: Fix INTx fallback when MSI fails
commit dc8bf1b1a6edfc92465526de19772061302f0929 upstream.
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.
