[PATCH] iommu/vt-d: Drop "0x" prefix from PCI bus & device addresses

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

719a19335692 ("iommu/vt-d: Tweak the description of a DMA fault") changed
the DMA fault reason from hex to decimal.  It also added "0x" prefixes to
the PCI bus/device, e.g.,

  - DMAR: [INTR-REMAP] Request device [00:00.5]
  + DMAR: [INTR-REMAP] Request device [0x00:0x00.5]

These no longer match dev_printk() and other similar messages in
dmar_match_pci_path() and dmar_acpi_insert_dev_scope().

Drop the "0x" prefixes from the bus and device addresses.

Fixes: 719a19335692 ("iommu/vt-d: Tweak the description of a DMA fault")
