[PATCH] printk: modify console_unlock with printk-safe macros

[Pierre Kuo]

From: pierre Kuo <vichy....@gmail.com>

In commit de6fcbdb68b2 ("printk: convert the rest to printk-safe"), we
create 4 helper macros to make printk-safe usage easier.
Here we modify some part of console_unlock with above marcros.
