drm/i915: Use cpu relocations if the object is in the GTT but not mappable
commit 504c7267a1e84b157cbd7e9c1b805e1bc0c2c846 upstream.
This prevents the case of unbinding the object in order to process the
relocations through the GTT and then rebinding it only to then proceed
to use cpu relocations as the object is now in the CPU write domain. By
choosing to use cpu relocations up front, we can therefore avoid the
rebind penalty.
