Eric Auger 1084feddc6 virtio-iommu: Standardize granule extraction and formatting 
At several locations we compute the granule from the config
page_size_mask using ctz() and then format it in traces using
BIT(). As the page_size_mask is 64b we should use ctz64 and
BIT_ULL() for formatting. We failed to be consistent.

Note the page_size_mask is garanteed to be non null. The spec
mandates the device to set at least one bit, so ctz64 cannot
return 64. This is garanteed by the fact the device
initializes the page_size_mask to qemu_target_page_mask()
and then the page_size_mask is further constrained by
virtio_iommu_set_page_size_mask() callback which can't
result in a new mask being null. So if Coverity complains
round those ctz64/BIT_ULL with CID 1517772 this is a false
positive
