drm/tegra: Use drm_gem_object_unreference_unlocked()
This only grabs the mutex when really needed, but still has a might-
acquire lockdep check to make sure that's always possible. With this
patch Tegra DRM is officially struct_mutex free, yay!
v2: refernce_unlocked doesn't exist as kbuild spotted.
