sna: Treat external bo carefully when marking as idle
When we flag a bo as being externally modified, we set a special flag on
its request pointer. This forces us to inspect whether the bo is busy
before accessing it the next, and if it is idle, we must be careful that
we then do not dereference the special request.
Fixes regression from
