Handle incoming ObjectImage (TextureEntry) updates synchronously rather than asynchronously

At least on stock Linden clients, updating the texture on all faces of the prim will actually send an ObjectImage packet for each update.
There is a race condition if these are handled async, meaning that occasionally not all of the faces are correctly updated.
