ofproto: Fix potential NULL dereference in ofproto_get_datapath_cap().
Reproducer:
ovs-vsctl \
-- add-br br \
-- set bridge br datapath-type=foo \
-- --id=@m create Datapath datapath_version=0 'capabilities={}' \
-- set Open_vSwitch . datapaths:"foo"=@m
Fixes: 27501802d09f ("ofproto-dpif: Expose datapath capability to ovsdb.")
