When msm_iommu_meta_create() returns error, msm_iommu_map_mutex is not
getting unlocked and error pointer is being passed to
msm_iommu_meta_put(). Fix this.

In error situations, iommu_meta remains NULL and msm_iommu_meta_put()
gets called with this NULL pointer. Fix this.

The msm iommu mapping wrappers use reference counting which
make returning an error code impossible. Loudly warn instead
to make certain problems more obvious.

Apart from just mapping Ion buffers, we want to be able to
map dma_bufs as well. Support those APIs.

The IOMMU mapping APIs used to be tied to Ion but there
is less of a dependency these days. Move the file out of
the Ion directory and to somewhere more generic.
