Subject: [TG3 1/8]: Save MSI state before suspend.

[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.
