net: bridge: vlan: drop legacy memory barriers

Browse source

These memory barriers are legacy code from the old vlan implementation
that is not needed anymore. They're also affecting the fast-path.
The pvid is changed under lock and is read with rcu only in the fast-path
there is no need for a barrier, nothing to commit prior to changing it nor
invalidate prior to reading.
