drm/i915/gem: Remove shared locking on freeing objects
The obj->base.resv may be shared across many objects, some of which may
still be live and locked, preventing objects from being freed
indefintely. We could individualise the lock during the free, or rely on
a freed object having no contention and being able to immediately free
the pages it owns.
