[PATCH net-next] dccp: Convert DCCP_WARN to net_warn_ratelimited

Remove the dependency on the "warning" sysctl (net_msg_warn)
which is only used by the LIMIT_NETDEBUG macro.

Convert the LIMIT_NETDEBUG use in DCCP_WARN to the more
common net_warn_ratelimited mechanism.

This still ratelimits based on the net_ratelimit()
function, but removes the check for the sysctl.

Applied, thanks for doing this work Joe.

No worries.

What about the LIMIT_NETDEBUG stuff now?

Maybe all of them might as well be net_dbg_ratelimited
even if it changes some of the logging levels.

Probably DCCP_WARN should be net_warn_ratelimited
so let's start there...
