drm/gem: switch dev->object_name_lock to a mutex I want to wrap the creation of a dma-buf from a gem object in it, so that the obj->export_dma_buf cache can be atomically filled in. Instead of creating a new mutex just for that variable I've figured I can reuse the existing dev->object_name_lock, especially since the new semantics will exactly mirror the flink obj->name already protected by that lock. v2: idr_preload/idr_preload_end is now an atomic section, so need to move the mutex locking outside.
