drm/i915: Unalias obj->phys_handle and obj->userptr
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.
Testcase: igt/gem_userptr_blits/forbidden-operations
