afs: Fix missing lock when replacing VL server list
When afs_update_cell() replaces the cell->vl_servers list, it uses RCU
protocol so that proc is protected, but doesn't take ->vl_servers_lock to
protect afs_start_vl_iteration() (which does actually take a shared lock).
Fix this by making afs_update_cell() take an exclusive lock when replacing
->vl_servers.
