init/Kconfig: Hide printk log config if CONFIG_PRINTK=n
commit 361e9dfbaae84b0b246ed18d1ab7c82a1a41b53e 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]
