mm/mempolicy.c: fix indentation of the comments of do_migrate_pages

Currently, do_migrate_pages() have very long comment and this is not
indent properly.  I often misunderstand it is function starting commnents
and confused it.

this patch fixes it.

note: this patch doesn't break 80 column rule. I guess original
      author intended this indentaion, but an accident corrupted it.
