[PATCH v2 0/2] iommu/amd/iommu_v2: Fix refcount related issues

[Vasant Hegde <vasant.hegde@amd.com>]

This patch series fixes the refcount warning and pasid state in free
path.

V1 : https://lore.kernel.org/linux-iommu/20230124104355.119166-1-vasant.hegde@amd.com/

@Jason, Joerg,
  During v1 series review Jason had suggested few things including
  moving to xarray to handle PASID. We are planning to implement
  xarray as separate series.

  This series fixes the kernel warning we are seeing because of
  commit 8bc54824da4e. I am keeping changes as minimal so that
  its easy to backport.

Base commit: d11370bf64c57a (iommu/next branch)
