net: bridge: mst: Restrict info size queries to bridge ports

Ensure that no bridge masters are ever considered for MST info
dumping. MST states are only supported on bridge ports, not bridge
masters - which br_mst_info_size relies on.

Fixes: 122c29486e1f ("net: bridge: mst: Support setting and reporting MST port states")
