igb: remove ASPM L0s workaround
The L0s workaround should be moved into a pci quirk and so it is not necessary in the driver. This update removes the L0s workaround from the igb driver. This was the second half of the PCI quirk patch that Matthew Wilcox did not pick up when he picked up the quirk patch.
