myri10ge: match number of save_state and restore
Since pci_save_state() pushes MSI and PCIe states on a kind of stack, myri10ge saving the state in advance for parity recovery will push the state again on the stack on suspend. This leads to some memory leak. We add a couple additional calls to save_state and restore_state so that we don't leak anymore. For the future, we are thinking of a better way to recover from parity error without using pci_save_state(). Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
