mm/rmap: use rmap_walk() in try_to_unmap()
Now, we have an infrastructure in rmap_walk() to handle difference from variants of rmap traversing functions. So, just use it in try_to_unmap(). In this patch, I change following things. 1. enable rmap_walk() if !CONFIG_MIGRATION. 2. mechanical change to use rmap_walk() in try_to_unmap().
