Non-debugging message text should be (and is in the cases here)
distinguishable without also logging function names. Additionally log
the PCI device coordinates for alloc_pdev() failure.

On this note, I have a series I never really started properly, which
introduces a single pci_sbdf_t, totalling 32 bits of bitfields, and a
custom %p handler. The register shuffling required in all the function
calls taking 4 parameters for the PCI SBDF which total 32 bits seems
extremely wasteful.

Oh, yes, I've been meaning to get to this too, but never really did.
