printk: Do not miss new messages when replaying the log
[ Upstream commit f92b070f2dc89a8ff1a0cc8b608e20abef894c7d ]
The variable "exclusive_console" is used to reply all existing messages
on a newly registered console. It is cleared when all messages are out.
The problem is that new messages might appear in the meantime. These
are then visible only on the exclusive console.
The obvious solution is to clear "exclusive_console" after we replay
all messages that were already proceed before we started the reply.
