AMD IOMMU: fix find_iommu_from_bdf_cap()

The arguments passed for the "cap_offset" parameter get read from 16-
bit fields, so the parameter should also have (at least) 16 bits.

While fixing this I also noticed that this was yet another case where
PCI segment information wasn't properly propagated, so a respective
first parameter gets added to the function at once.
