[PATCH rc 0/2] Fix maps created without READ or WRITE

I noticed some bugs here while working on iommupt. Fix them up.

Joerg, can you pick this both for your -rc branch?

Thanks,
Jason

  iommufd: Do not allow creating areas without READ or WRITE
  iommu: Do not return 0 from map_pages if it doesn't do anything
