Joerg Roedel 05df1f3c2a iommu/msm: Fix error handling in msm_iommu_unmap()
Error handling in msm_iommu_unmap() is broken. On some error
conditions retval is set to a non-zero value which causes
the function to return 'len' at the end. This hides the
error from the user. Zero should be returned in those error
cases.
