drm/rockchip: don't leak iommu mapping
arm_iommu_attach_device() takes its own reference to the mapping we give
it. Since we do not keep a reference to the mapping ourselves, we must
release it before returning.
Also fix the error path, which fails to release the mapping if it has
called arm_iommu_detach_device() since that clears archdata.mapping.
