[TG3]: Save MSI state before suspend.
This fixes the following problem: http://bugzilla.kernel.org/show_bug.cgi?id=7969 The MSI state needs to be saved during suspend. PCI state saved during tg3_init_one() does not contain valid MSI state because MSI hasn't been enabled. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
