I think it is ok the way it is.  We call pci_restore_state() at least
once during tg3_chip_reset().  This will free any memory allocated
during tg3_init_one()'s call to pci_save_state(), before we even get to
tg3_suspend().

The memory allocated in tg3_suspend()'s call to pci_save_state() will be
freed when tg3_resume() calls pci_restore_state().
