[PATCH RFC 16/19] mm/frame-vector: remove FOLL_FORCE usage

[David Hildenbrand]

FOLL_FORCE is really only for debugger access. According to commit
707947247e95 ("media: videobuf2-vmalloc: get_userptr: buffers are always
writable"), the pinned pages are always writable.

FOLL_FORCE in this case seems to be a legacy leftover. Let's just remove
it.
