net: dsa: Fix tagging attribute location While introducing the DSA tagging protocol attribute, it was added to the DSA slave network devices, but those actually see untagged traffic (that is their whole purpose). Correct this mistake by putting the tagging sysfs attribute under the DSA master network device where this is the information that we need. While at it, also correct the sysfs documentation mistake that missed the "dsa/" directory component of the attribute.

net: dsa: Expose tagging protocol to user-space There is no way for user-space to know what a given DSA network device's tagging protocol is. Expose this information through a dsa/tagging attribute which reflects the tagging protocol currently in use. This is helpful for configuration (e.g: none behaves dramatically different wrt. bridges) as well as for packet capture tools when there is not a proper Ethernet type available.
