Aashish Sharma 055e892aac iommu/vt-d: Fix unused invalidation hint in qi_desc_iotlb 
[ Upstream commit 6b38a108ee ]

Invalidation hint (ih) in the function 'qi_desc_iotlb' is initialized
to zero and never used. It is embedded in the 0th bit of the 'addr'
parameter. Get the correct 'ih' value from there.

Fixes: f701c9f36b ("iommu/vt-d: Factor out invalidation descriptor composition")
