net: dsa: use temporary dsa_device_ops variable
When resolving the DSA tagging protocol used by a CPU switch, use a temporary "tag_ops" variable to store the dsa_device_ops instead of using directly dst->tag_ops. This will make the future patches moving this pointer around easier to read. There is no functional changes.
