The offset got dropped by accident.
Fixes: d413e6f97134 ("drm/msm: Drop msm_gem_iova()")

Nit: can we push fb->offsets handling into msm_framebuffer_prepare()
instead? Then the msm_framebuffer_iova() would become trivial?

I'd briefly considered it, but ended up putting it here simply because
that is where the offset addition was prior to d413e6f97134. Whether
that is a good reason or not, idk. (Prior to d413e6f97134 it needed
to be here, now it doesn't)
