net: openvswitch: silence suspicious RCU usage warning
ovs_flow_tbl_destroy always is called from RCU callback
or error path. It is no need to check if rcu_read_lock
or lockdep_ovsl_is_held was held.
ovs_dp_cmd_fill_info always is called with ovs_mutex,
So use the rcu_dereference_ovsl instead of rcu_dereference
in ovs_flow_tbl_masks_cache_size.
Fixes: 9bf24f594c6a ("net: openvswitch: make masks cache size configurable")
