printk: nbcon: Flush new records on device_release()
There may be new records that were added while a driver was
holding the nbcon context for non-printing purposes. These
new records must be flushed by the nbcon_device_release()
context because no other context will do it.
If boot consoles are registered, the legacy loop is used
(either direct or per irq_work) to handle the flushing.
