Colin Ian King b9b2092af3 iommu/omap: Check for failure of a call to omap_iommu_dump_ctx 
[ Upstream commit dee9d154f40c58d02f69acdaa5cfd1eae6ebc28b ]

It is possible for the call to omap_iommu_dump_ctx to return
a negative error number, so check for the failure and return
the error number rather than pass the negative value to
simple_read_from_buffer.
