PCI: vmd: Fix inconsistent indentation in vmd_resume()

The if-statement within the vmd_resume() function has an inconsistent
indentation that leads to a compile time warning.

Thus, correct the inconsistent indentation.  While at it, remove the
if-statement completely, which will make the code simpler.

This was detected by Smatch:

  drivers/pci/controller/vmd.c:1066 vmd_resume() warn: inconsistent indenting

No functional changes are intended.
