Subject: [net-2.6 PATCH] e1000e/igb/ixgbe: Don't report an error if devices
	don't support AER

From: Frans Pop <elendil@...net.nl>

The only error returned by pci_{en,dis}able_pcie_error_reporting() is
-EIO which simply means that Advanced Error Reporting is not supported.
There is no need to report that, so remove the error check from e1000e,
igb and ixgbe.
