[PATCH] add missing pci_disable_device for e1000

From: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com>

This patch adds pci_disable_device() into e1000_remove().

If your driver decides to stop using the device, it should call
pci_disable_device() to deallocate any IRQ resources, disable PCI
bus-mastering, etc.
