ixgbe: fix Need to call pci_save_state after pci_restore_state



This patch adds a pci_save_state() call in ixgbe_resume() after
pci_restore_state(). A similar change was made in ixgbe_io_slot_reset()
that accommodates pci_restore_state() new behavior. This change makes
pci_restore_state() clear the saved_state flag This is necessary due
to a resent kernel change to pci_restore_state() so that it now clears
the saved_state flag of the device right after the device.s standard
configuration registers have been poplulated with the previously saved
values.
