Minchan Kim c2b7c24bc1 ANDROID: mm: page_pinner: unattribute follow_page in munlock_vma_pages_range ...

munlock_vma_pages_range uses follow_page(FOLL_GET) so we need to use
put_user_page to avoid false positive. However, munlock path is quite
complicated to attribute them. At this point, do not make the muck.
Instead just unattribute them to avoid false positive.
