Git-commit: d730e4bd3a4154912eba812be756014abccfe28e
Patch-mainline: Queued in subsystem maintainer repository
References: SLE Realtime Extension

If messages which are injected via kmsg are dropped then they don't need
to be printed as warnings. This is to avoid latency spikes if the
interface decides to print a lot of important messages.
