Socket errors logged despite being set to off

[kkmuffme]

lua_socket_log_errors off;

However, I still get this in redis error log:

[crit] 2892523#2892523: *4122 connect() to unix:/var/run/redis3/redis3.sock failed (2: No such file or directory)

Seems to be same/related to openresty/lua-nginx-module#1613
