PCI: vmd: Fix indentation issue in vmd_shutdown()

The code in vmd_shutdown() had an indentation issue where spaces were
used instead of tabs. This commit corrects the indentation to use tabs,
adhering to the Linux kernel coding style guidelines.

Issue reported by the checkpatch.pl script:

  ERROR: code indent should use tabs where possible
  #1056: FILE: drivers/pci/controller/vmd.c:1056:
  +        struct vmd_dev *vmd = pci_get_drvdata(dev);$

  WARNING: please, no spaces at the start of a line
  #1056: FILE: drivers/pci/controller/vmd.c:1056:
  +        struct vmd_dev *vmd = pci_get_drvdata(dev);$

  ERROR: code indent should use tabs where possible
  #1058: FILE: drivers/pci/controller/vmd.c:1058:
  +        vmd_remove_irq_domain(vmd);$

  #1058: FILE: drivers/pci/controller/vmd.c:1058:
  +        vmd_remove_irq_domain(vmd);$

No functional changes are intended.
