[PATCH 2/2]: e1000 disable device on PCI error

[Linas Vepstas]

Same as last patch, but for the e1000 gigabit card.

A recent patch in -mm3 titled 
 "gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch"
causes pci_enable_device() to be a no-op if the kernel thinks
that the device is already enabled.  This change breaks the
PCI error recovery mechanism in the e1000 device driver, since, 
after PCI slot reset, the card is no longer enabled. This is 
a trivial fix for this problem. Tested.

Please submit uptream.
