PCI: Release IVRS table in AMD ACS quirk

PCI: Release IVRS table in AMD ACS quirk

[ Upstream commit 090688fa4e448284aaa16136372397d7d10814db ]

The acpi_get_table() should be coupled with acpi_put_table() if the mapped
table is not used at runtime to release the table mapping.

In pci_quirk_amd_sb_acs(), IVRS table is just used for checking AMD IOMMU
is supported, not used at runtime, so put the table after using it.

Fixes: 15b100dfd1c9 ("PCI: Claim ACS support for AMD southbridge devices")
