Interface custom `speed` isn't being set in certain port status cases

[viniarck]

Interface with speed none after re connection and/or when a new interface gets created with OFPPR_ADD (such as a logical that is dynamically created), currently the runtime is prepared to have speed:float = None, but topology datamodel isn't, we could also allow it there, but if you analyze the code, it's always possible to derive the current speed with OpenFlow messages, however, we're not setting the fallback speed when handling a port status in certain cases

This is an issue that @italovalcy and @renatafrez has caught in prod

Priority major since it can crash and impact on a DB write
