etnaviv: drm: properly handle reviving BOs via a lookup


If a BO is removed from a cache bucket list via a lookup, we must
handle it in the same way as if a allocation from the cache happened:
tell valgrind that the buffer is active again and take a reference
to the etna_device, which the BO had given up while being in the
cache.
