Summary
net: bridge: mst: fix suspicious rcu usage in br_mst_set_state
Details

In the Linux kernel, the following vulnerability has been resolved:

net: bridge: mst: fix suspicious rcu usage in brmstset_state

I converted brmstset_state to RCU to avoid a vlan use-after-free but forgot to change the vlan group dereference helper. Switch to vlan group RCU deref helper to fix the suspicious rcu usage warning.
