kmsg: make sure all messages reach a newly registered boot console
We suppress printing kmsg records to the console, which are already printed immediately while we have received their fragments. Newly registered boot consoles print the entire kmsg buffer during registration. Clear the console-suppress flag after we skipped the record during its first storage, so any later print will see these records as usual.
