ixgbe: move ixgbe_clear_interrupt_scheme to before pci_save_state

Browse source 
The main reason for this change is to keep the suspend/resume logic matched
up. The clear_interrupt_scheme function will disable MSI-X which will
effect the PCIe configuration space. Therefore we will want to do it before
we save state to avoid having the interrupt state restored by
pci_restore_state, and then trying to re-enable MSI/MSI-X interrupts via
ixgbe_setup_interrupt_scheme.
