igb: Use extended interrupt mode whenever possible
The extended interrupt mode could be used as long as the interrupt
is not shared. MSI by definition is not shared. For line interrupt,
hw.igbX.irq.unshared tunable is added; it could be set, if the igbX
does not share interrupt line with other devices.
The extended interrupt mode could deliver accurate information about
which queue is active, thus avoiding extra memory reading.
