Vladimir Oltean 5454f5c28e net: bridge: vlan: check for errors from __vlan_del in __vlan_flush 
If the following call path returns an error from switchdev:

nbp_vlan_flush
-> __vlan_del
   -> __vlan_vid_del
      -> br_switchdev_port_vlan_del
-> __vlan_group_free
   -> WARN_ON(!list_empty(&vg->vlan_list));

then the deletion of the net_bridge_vlan is silently halted, which will
trigger the WARN_ON from __vlan_group_free().

The WARN_ON is rather unhelpful, because nothing about the source of the
error is printed. Add a print to catch errors from __vlan_del.
