[PATCH 6/8] IOMMU: log appropriate SBDF

[Jan Beulich]

To handle phantom devices, several functions are passed separate "devfn"
arguments besides a PCI device. In such cases we want to log the phantom
device's coordinates instead of the main one's. (Note that not all of
the instances being changed are fallout from the referenced commit.)

Fixes: 1ee1441835f4 ("print: introduce a format specifier for pci_sbdf_t")
