A small set of fixes for x86:

 - Cure the fallout from the MSI irqdomain overhaul which missed that the
   Intel IOMMU does not register virtual function devices and therefore
   never reaches the point where the MSI interrupt domain is assigned. This
   makes the VF devices use the non-remapped MSI domain which is trapped by
   the IOMMU/remap unit.

 - Remove an extra space in the SGI_UV architecture type procfs output for
   UV5.

 - Remove a unused function which was missed when removing the UV BAU TLB
   shootdown handler.
