[PATCH stable 4.9 1/4] printk: Export is_console_locked

[Chen Jun <chenjun102@huawei.com>]

From: Hans de Goede <hdegoede@redhat.com>

commit d48de54a9dab5370edd2e991f78cc7996cf5483e upstream

This is a preparation patch for adding a number of WARN_CONSOLE_UNLOCKED()
calls to the fbcon code, which may be built as a module (event though
usually it is not).
