Subject: [PATCH 4.19 18/32] iommu/iova: Fix compilation error with !CONFIG_IOMMU_IOVA

From: Joerg Roedel <jroedel@...e.de>

commit 201c1db90cd643282185a00770f12f95da330eca upstream.

The stub function for !CONFIG_IOMMU_IOVA needs to be
'static inline'.

Fixes: effa467870c76 ('iommu/vt-d: Don't queue_iova() if there is no flush queue')
