Nikolay Aleksandrov a6cc9e9a65 net: bridge: mst: pass vlan group directly to br_mst_vlan_set_state 
[ Upstream commit 36c92936e868601fa1f43da6758cf55805043509 ]

Pass the already obtained vlan group pointer to br_mst_vlan_set_state()
instead of dereferencing it again. Each caller has already correctly
dereferenced it for their context. This change is required for the
following suspicious RCU dereference fix. No functional changes
intended.
