Fix races in cancel update

There is issue in nova with detaching port from a server.
Sometimes nova can delete a port instead of detach it. This situation
happens if we ask nova to detach port from a server that was moved
to active state right before detach was called. So, we can wait some
time before detach the port. This hopefully fix the problem in the most
situations.
