Subject: [net-next-2.6 PATCH 2/2] e1000: call pci_save_state after
	pci_restore_state

From: Nick Nunley <nicholasx.d.nunley@...el.com>

This patch adds a call to pci_save_state() immediately after
the call to pci_restore_state(). Due to a change in the behavior
of pci_restore_state() it is necessary to call pci_save_state()
to keep the state_saved flag. This patch is based on a similar
patch for ixgbe.
