intel-iommu: mark intel_dma_ops static
ia64 currently explicitly assigns it to dma_ops, but that same work is already done by intel_iommu_init a little later, so we can remove the duplicate assignment and mark the variable static. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Tony Luck <tony.luck@intel.com>
