igb: Partly rework MSI-X support to bypass one serializer
For aggregated TX/RX MSI-X handler, there is no need to use
an independent serializer; using RX ring's serializer just
works (well, this driver's MSI-X support was added when we
still lacked of experience about how to serialize aggregated
TX/RX MSI-X handler).
Enable aggregated TX/RX MSI-X handling by default to avoid
extra TX interrupt (though its pretty low for TCP streams).
