[GIT PULL] printk fix for 4.12-rc5

[Petr Mladek]

Linus,

please pull a printk regression fix from:

  git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk.git for-linus

========

It reverts a fix added into 4.12-rc1. It caused the kernel log to
be printed on another console when two consoles of the same type were
defined, e.g. console=ttyS0 console=ttyS1. This configuration was
never supported by kernel itself. But it started to make sense with
systemd. By other words, the commit broke userspace.
