s2io: fixing a ethtool test that is broken

Due commit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff, it is not more
possible to pci_restore_state() more than once without calling
pci_save_state() in the middle.

Actually running a ethtool test on s2io makes the card inactive,
and it needs to unload/reload the module to fix.

This patch just save the state just after it restore in order to
keep the old behaviour
