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.

[bwh: Backported to 3.2: drop change to CONFIG_LOG_CPU_MAX_BUF_SHIFT]
