init/Kconfig: Hide printk log config if CONFIG_PRINTK=n

commit 361e9dfbaa upstream.

The buffers sized by CONFIG_LOG_BUF_SHIFT and
CONFIG_LOG_CPU_MAX_BUF_SHIFT do not exist if CONFIG_PRINTK=n, so don't
ask about their size at all.

[lizf: Backported to 3.4:
 - drop the change to CONFIG_LOG_CPU_MAX_BUF_SHIFT as it doesn't exist in 3.4]
