Revert "Log an error if getstats() returns a failure"

This reverts commit 8266da9c.

We're already passing a sock_init callback (ls_cb) which is supposed to set
the socket options (call set_socket_options), so this change shouldn't be
necessary and reportedly caused more issues binding ircd sockets when running
ircd.js via jsexec (though I didn't see this myself).
