iommu/vt-d: Eliminate pci_physfn() in dmar_find_matched_satc_unit()

Browse Source 
The function dmar_find_matched_satc_unit() contains a duplicate call to
pci_physfn(). This call is unnecessary as pci_physfn() has already been
invoked by the caller. Removing the redundant call simplifies the code
and improves efficiency a bit.
