Alexander Shishkin 88cfd822f9 intel_th: msu: Fix single mode with IOMMU ...

commit 4e0eaf239f upstream.

Currently, the pages that are allocated for the single mode of MSC are not
mapped into the device's dma space and the code is incorrectly using
*_to_phys() in place of a dma address. This fails with IOMMU enabled and
is otherwise bad practice.

Fix the single mode buffer allocation to map the pages into the device's
DMA space.
