[PATCH] mm/page_poison: Make early_page_poison_param __init

[Dou Liyang <douly.fnst@cn.fujitsu.com>]

The early_param() is only called during kernel initialization, So Linux
marks the function of it with __init macro to save memory.

But it forgot to mark the early_page_poison_param(). So, Make it __init
as well.
