[PATCH v1 2/3] drm/tegra: uapi: Fix wrong mapping end address in case of disabled IOMMU

[Dmitry Osipenko <digetx@gmail.com>]

All jobs are failing on Tegra20 because it doesn't use IOMMU and mapping
function uses size of mapping that is zero instead of BO size, fix it.

Fixes: d7c591bc1a3f ("drm/tegra: Implement new UAPI")
