net: stmmac: replace priv->speed with the portTransmitRate from the tc-cbs parameters
The current cbs parameter depends on speed after uplinking, which is not needed and will report a configuration error if the port is not initially connected. The UAPI exposed by tc-cbs requires userspace to recalculate the send slope anyway, because the formula depends on port_transmit_rate (see man tc-cbs), which is not an invariant from tc's perspective. Therefore, we use offload->sendslope and offload->idleslope to derive the original port_transmit_rate from the CBS formula.
