This deprecates get_locked_port_and_binding and removes
its usage from ML2.
This function was misleading because it uses with_lockmode('update')
which does not actually block concurrent uses in galera multi-writer
deployments. A lock violation in multi-writer will manifest as a
deadlock at that end.
The revision service plugin already provides us with protection from
concurrent updates within a transaction via a compare and swap on the
revision number that will manifest as a staledataerror in races. This
error can then be retried by the retry decorator in the same way a
deadlock on multi-writer would.
This also will help us avoid trying to carry this db locking into
oslo versioned objects.
