ksm: use precise linear_page_index instead of the whole address space
Since we now have linear_page_index available that we can use here,
allowing for optimizing the RMAP walk, we can also use it to locate more
precisely all related-processes when error hits the KSM page, which will
decrease a lot of invalid iterations.
