datapath: Convert dp rcu read operation to locked operations
dp read operations depends on ovs_dp_cmd_fill_info(). This API needs to looup vport to find dp name, but vport lookup can fail. Therefore to keep vport reference alive we need to take ovs lock. Found by code inspection. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Acked-by: Andy Zhou <azhou@nicira.com>
