printk: Use console_is_usable on console_unblank

Browse source

The macro for_each_console_srcu iterates over all registered consoles. It's
implied that all registered consoles have CON_ENABLED flag set, making
the check for the flag unnecessary. Call console_is_usable function to
fully verify if the given console is usable before calling the ->unblank
callback.
