ixgbe: Refactor MSI-X allocation mechanism
Our current MSI-X allocation mechanism does not support new hardware
at all. It also isn't getting the actual number of supported MSI-X vectors
from the device.
This patch allows the number of MSI-X vectors to be specific to a device,
plus it gets the number of MSI-X vectors available from PCIe configuration
space.
