[PATCH 4.9 16/51] iommu/vt-d: Use memunmap to free memremap

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 829383e183728dec7ed9150b949cd6de64127809 ]

memunmap() should be used to free the return of memremap(), not
iounmap().

Fixes: dfddb969edf0 ('iommu/vt-d: Switch from ioremap_cache to memremap')
