Chris Wilson 89758797f1 drm/i915: Unalias obj->phys_handle and obj->userptr ...

commit ca5732c53b upstream.

We use obj->phys_handle to choose the pread/pwrite path, but as
obj->phys_handle is a union with obj->userptr, we then mistakenly use
the phys_handle path for userptr objects within pread/pwrite.
