Set vertex_buffer_bo to NULL after unreference. 

Which is just being tidy. We initially were looking at this code
path due to a report of a crash on server shutdown which started
after this unreference call was added. Setting this to NULL
apparently didn't avoid the crash, but it's a good thing to do
regardless.
