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().
