The bridge VLANs are not offloaded by dsa_port_vlan_* if the port is not bridged or if its bridge is not VLAN aware. This is a good thing but other corners of DSA, such as the tag_8021q driver, may need to program VLANs regardless the bridge state. And also because bridge_dev is specific to user ports anyway, move these checks were it belongs, one layer up in the slave code.
