Andre Przywara f44efca049 vfio: Ignore -ENODEV when getting MSI cookie ...

When we try to get an MSI cookie for a VFIO device, that can fail if
CONFIG_IOMMU_DMA is not set. In this case iommu_get_msi_cookie() returns
-ENODEV, and that should not be fatal.

Ignore that case and proceed with the initialisation.

This fixes VFIO with a platform device on the Calxeda Midway (no MSIs).
